General Guidelines to the examination of DUS and the
development of harmonized descriptions of plant varieties
1. GENERAL INTRODUCTIONAgriculture is the prime mover of the Indian economy, largest employer, biggest and very old
enterprise. The rapid agricultural growth from mid 1960s that brought about transformation in theproduction system and genetic improvement of plants are some of the important factors that transformedIndia’s agriculture. In many crops large number of land races, farmers’ varieties and scientifically developedcultivars existed in the 19th and early part of the 20th century and much of it have been replaced by newand better varieties. This large-scale loss of varieties that happened globally is a matter of concern eventhough loss of diversity does not necessary mean loss of genes. Definitely, some loss of genetic diversityhappened since the World War I. In order to contain the loss of genetic diversity and sustain agriculturalgrowth and to position India to get maximum advantage, several steps have been taken. The “Protectionof Plant Varieties and Farmers’ Rights Act” was passed by the Parliament in 2001 which is a significantleap forward. In the long run it would facilitate the growth of the seed industry and make available highquality seeds and planting material to the farmers. Implementation of the Act will accelerate agriculturaldevelopment; protect plant breeder’s rights for creating new plant varieties through higher research anddevelopment investments in both public and private plant breeding. Above all it will protect the rights ofthe farmers for the contributions made in conserving, improving and making available plant geneticresources for the development of new varieties.
India ratified the Agreement on Trade Related Aspects of the Intellectual Property Rights (TRIPs)and for purposes of safeguarding our interests and meeting our obligations under the TRIPs an ordinanceto amend the Patent Act, 1970 was promulgated in 1994. India has the observer status in the UPOV(Union Internationale Pour La Protection Des Obtentions Vegetales), an international organization forthe protection of new varieties of plants with its main office at Geneva, Switzerland. The TRIPs agreementunder 27(3) (b) gives an option to member countries to adopt an effective “sui generis” system for plantvariety protection. By adopting a system in the context of UPOV (1978) the PPV&FR Act, 2001 hasbeen made as a widely acceptable registration system.
The plant breeder driven varietal development program generally is rewarding under the well managedhigh input agriculture that is practiced by the affordable farmers. The locally grown varieties or mixtureof varieties cultivated by the poor farmers are well adapted to local growing situations. This rich germplasmconserved, selected, assessed and community shared, often serve as donor lines to breed commerciallyacceptable high yielding new varieties.
The realization of the Farmers’ Rights was highlighted by UNCED in its Agenda 21 and by the Conventionon Biodiversity. The FAO conference in 1993 adopted resolution 7/93 calling for the renegotiation,including the realization of Farmers’ Rights.
The farmers’ rights has several dimensions; compensation for innovations evident from thedevelopment of farmers’ varieties; compensation for making the genetic resources available and provision
128 Volume 1, No. 1
of incentives to continuously sustain it. In fact, there is continuity between the farmer-conserved germplasmand the plant breeder bred new varieties, as one is dependent on the other. Farmers or their communitieshave a right to keep, use, exchange, share, and sell their seeds or planting material. Hence the PPV&FRAretains the basic spirit of the UPOV. As custodians of plant genetic resources and related indigenous andlocal knowledge farmers should have their rights protected and should have access to benefit sharing forthe new material developed out of/using, farmer’s variety. Many nations feel the need for a legal frameworkfor the farmers’ rights and opine that the Indian ‘sui generis’ system accommodates the requirements ofvarying and diverse needs. This “General Guidelines” drew inspiration from the experience and framework material of UPOV.
2. ABOUT THE DOCUMENT2.1 After examination of the candidate variety (the variety of a given denomination applied for registration
under PPV&FR Act, 2001) has shown that it complies with the requirements for protection laiddown in the PPV&FR Act, 2001 and, in particular, that the variety is distinct (D) from other varietywhose existence is a matter of common knowledge at the time of the filing of the application andthat it is sufficiently uniform (U) and stable (S), or “DUS” in short the candidate variety will beentertained for DUS test and registration. The examination, or “DUS Test,” is based mainly ongrowing tests, carried out by the authority competent for granting plant breeders’ rights or by separateinstitutions, such as public research institutes, acting on behalf of that authority or, in some cases, onthe basis of growing tests carried out by the breeder. The examination generates a description of thevariety, using its relevant characteristics (e.g. plant height, leaf shape, flower and fruit characters, bywhich it can be defined as a variety in terms of the above said Act.
2.2 The purpose of this document (hereinafter referred to as the “General Guidelines”), and the associatedseries of Specific Guidelines’ (hereinafter referred to as the “SG Documents”), is to set out theprinciples, which are used in the examination of DUS. The identification of those principles ensuresthat examination of candidate varieties is conducted in a harmonized way to provide effectiveprotection through the development of harmonized internationally recognized descriptions ofprotected varieties.
2.3 The binding obligations are that this document must not be interpreted in a way that is inconsistentwith the PPV&FR Act 2001. This General Guideline attempts to provide guidance for the examinationof all species in accordance with the above said Act, 2001 Further more the PPV&FR Authority hasdeveloped “Guidelines for the Conduct of Species Specific Distinctiveness, Uniformity and Stability,”tests or “ Specific Guidelines”, for individual species of plant. The purpose of these SpecificGuidelines is to elaborate certain of the principles contained in this document, into detailed practicalguidance for the harmonized examination of DUS and, in particular, to identify appropriatecharacteristics for the examination of DUS and production of harmonized variety descriptions.Specific Guidelines now proposed will be updated when new and additional information becomesavailable. Following this suit specific guideline for a large number of crops will be issued.
2.4 The individual Specific Guidelines were prepared with the assistance of the appropriate Task Force,that the PPV&FRA appointed having experts and professional consultants.
The knowledge and experience of breeders and the seed and plant industries were taken into accountand after series of consultations and discussions this General Guidelines was drafted. The list of individualSpecific Guidelines adopted and information on how to obtain copies of it from the PPV&FR Authorityis given in Annexure 1.
Plant Variety Journal of India 129
2.5 This document seeks to address all aspects related to DUS testing, in addition to providing guidanceon the development of Specific Guidelines.
2.6 Despite the Specific Guidelines being a detailed practical guidance on certain aspects of the exami-nation of DUS and identify appropriate characteristics for variety description, there are certain gen-eral aspects that apply across all Specific Guidelines, which is not necessary to reproduce in all theindividual Specific Guidelines.
2.7 In some situation the DUS examiner can use the basic principles contained in the General Guide-lines, rather than follow the detailed recommendations of the Specific Guidelines, where the cir-cumstances of the DUS examination determine that the recommended approach may not be themost appropriate for a particular set of conditions. Under such circumstances where the SpecificGuidelines are not followed, the DUS examiner should consider how to proceed in a way thatmaintains, as far as possible, harmonization in DUS examination and variety description for thatspecies.
2.8 In addition, the absence of Specific Guidelines for the species or variety grouping concerned willobviously lead the DUS examiner to resort to this General Guidelines, and there is a specific men-tion in column 10. (“Conduct of DUS Testing in the Absence of Specific Guidelines”) in this docu-ment for such an eventuality.
2.9 In conclusion, it is important for any DUS examiner to be familiar with the principles of DUSexamination set out in this document, and to consider them in conjunction with the appropriateindividual Specific Guidelines.
2.10 This document and the associated species specific ‘Specific Guidelines’ documents were reviewedby the Task Force 1/2005. Details of the current versions of all documents are available on PPV&FRAuthority website www.plantauthority.in in which readers are advised to consult if they are in doubtas to the validity of the documents in their possession.
3. THE EXAMINATION OF DISTINCTIVENESS, UNIFORMITY AND STABILITY (“DUSTESTING”)
3.1 Requirement for ExaminationThe PPV&FR Act, 2001 requires that a variety be examined for compliance with the distinctive-
ness, uniformity and stability criteria. It is further elaborated here that, during the course of the exami-nation, the DUS test center or the Authority may grow the variety or carry out other necessary tests,cause the growing of the variety or the carrying out of other necessary tests, or take into account theresults of growing tests or other trials which have already been carried out.
3.2 Test Guidelines as a Basis for DUS Testing3.2.1 Where Authority has established Specific Guidelines for a particular species, or other group(s) of
varieties, these represent an agreed and harmonized approach for the examination of new varietiesand, in conjunction with the basic principles contained in the General Guidelines, should form thebasis of the DUS test.
3.2.2 Where Authority has not established individual Specific Guidelines relevant to the variety to beexamined, the examination should be carried out in accordance with the principles in this documentand, in particular, the recommendations contained in Column 10.
130 Volume 1, No. 1
3.3 Design of the DUS TestsThe design of the growing trial or other tests, with regard to aspects such as the number of growing
cycles, layout of the trial, number of plants to be examined and method of observation, is largely deter-mined by the nature of the variety to be examined. Guidance on design is a key function of the SpecificGuidelines.
3.4 Characteristics as the Basis for Examination of DUS3.4.1 For any variety to be capable of protection it must first be clearly defined. Only after a variety has
been defined, it can be finally examined for fulfillment of the DUS criteria required for protection.The PPV&FR Act, 2001 under Section (15) a variety is defined by its characteristics and that thosecharacteristics are therefore, the basis on which a variety can be examined for DUS.
3.4.2 The Act further states in Section 2 (za) that a variety is a plant grouping that can be “defined by theexpression of the characteristics resulting from a given genotype of that plant grouping” and can be“distinguished from any other plant grouping by the expression of at least one of the said character-istics” and “Considered as a unit with regard to its suitability for being propagated which remainsunchanged after such propagation”. This covers as array of propagating material of such variety,extant variety, transgenic variety, farmers’ variety and essentially derived variety.
3.4.3 In addition to their use in defining a variety, characteristics are the basis for examining distinctive-ness, uniformity and stability.
3.4.4 In the PPV&FR Act 2001, Article 15 (3) (b) specifies that distinctiveness is established by a varietybeing “clearly distinguishable by at least one essential characteristic from any other variety whoseexistence is a matter of common knowledge in any country at the time of filling the applicationform,” while Article 15 (3) (d) requires it to be stable in its “essential characteristics” remain un-changed after repeated propagation or in case of a particular cycle of propagation, at the end of eachcycle. Although the term characteristic is not specified in the criteria for uniformity, it is clearlyimplied that the uniformity requirement relates to the characteristics of the variety, given that theyare the basis for distinctiveness and stability.
3.4.5 In the PPV&FR Act, 2001 Article 15(3) (c) states that uniformity is assessed on the basis of avariety being “sufficiently uniform in its relevant characteristics”. The requirement is that a variety“can be distinguished from any other plant grouping by the expression of at least one of the saidcharacteristics”.
3.5 Requirements of Material for DUS testing3.5.1 Representative Plant Material
The material to be submitted for the examination of DUS should be representative of the candidatevariety. In the case of varieties with a particular cycle of propagation, such as hybrid and syntheticvarieties, this means that the material tested should include the final stage in the cycle of propagation.
3.5.2 General Health of Submitted MaterialThe plant material submitted for examination should be visibly healthy, not lacking in vigor or affectedby any important pests or diseases and, in the case of seed, should have sufficient germination capacityfor the conduct of a satisfactory examination. The material submitted should be out of the recent harvestwith seed moisture levels that would permit medium long storage of the material in the low temperaturemodule. It should be free from any sort of physical or chemical treatment.
Plant Variety Journal of India 131
3.5.3 Factors that May Affect the Expression of the Characteristics of a Variety.The expression of a characteristic or several characteristics of a variety may be affected by factors,
such as pests and disease, chemical treatment (e.g. growth retardants or pesticides), effects of tissueculture, different rootstocks, scions taken from different growth phases of a tree, etc. In some cases (e.g.disease resistance), reaction to certain factors is intentionally used as a characteristic in the DUS exami-nation. However, where the factor is not intended for DUS examination, it is important that its influencedoes not distort the DUS examination. Accordingly, depending on the circumstances, the testing author-ity should ensure either that:
(a) The varieties under test are all free of such factors or,(b) That all varieties included in the DUS test, including varieties of common knowledge, are sub-
ject to the same factor and that it has an equal effect on all varieties or,(c) In cases where a satisfactory examination could still be undertaken, the affected characteristics
are excluded from the DUS examination unless the true expression of the characteristic of theplant genotype can be determined, notwithstanding the presence of the factor.
4. COOPERATION IN DUS TESTING4.1 Cooperation Between Testing Authorities4.1.1 Cooperation with other test sites and authorities can reduce the overall time, expense and number
of examiners involved in the DUS tests, and minimizes the work involved in the maintenance ofvariety collections. A “General Agreement” developed for this purpose by the Authority is meant toensure that DUS tests are conducted in a perfect manner.
4.1.2 The “centralized” DUS testing is on a regional or national basis, where the entire examination iscarried out on behalf of Authority regardless of the variety or the breeder concerned. This is pos-sible if the environment, whether natural or controlled, is suitable for the examination of all therelevant varieties.
4.2 Cooperation with Breeders4.2.1 In most situations variety testing is administered by an official authority as that, although the
breeders participate in the growing tests to varying degrees.
4.2.2 Close cooperation with breeders is being promoted by, PPV&FR Authority by linking the testsites, strengthening infra structures, competence and by sharing the benefits. They are required toconduct the DUS test and produce a test report in accordance with the principles contained in thisdocument. The decision on DUS may be based entirely on the test report supplied and the Authoritymay verify the results through Qualified Persons (QP). The QP will be designated persons, consult-ants by the Authority and if the Authority so desires, can ask them to visit the DUS site for jointrecording of the observations. The QP will be persons of high professional standing and ethics.
4.2.3 The Authority has drawn up a list of conditions for the examination of a variety on the basis ofDUS tests carried out by or on behalf of breeders.
5. CHARACTERISTICS USED IN DUS TESTING5.1 Characteristics as the Basis for DUS Testing
The basis for using characteristics for the examination of DUS is explained in Chapter 3, section3.4. The purpose of this Chapter is to set out the critical aspects of characteristics and their applicationsin proper conduct of DUS tests.
132 Volume 1, No. 1
5.2 Selection of Characteristics5.2.1 The basic requirements that a characteristic should fulfill before it is used for DUS testing or
producing a variety description are that its expression:
(a) Results from a given genotype or combination of genotypes;(b) Is sufficiently consistent and repeatable in a particular environment;(c) Exhibits sufficient variation between varieties to be able to establish distinctiveness;(d) Is capable of precise definition and recognition;(e) Allows uniformity requirements to be fulfilled;(f) Allows stability requirements to be fulfilled, meaning that it produces consistent and repeatable
results after repeated propagation or, where appropriate, at the end of each cycle of propagation.
5.2.2 It should be noted that there is no requirement for a characteristic to have any intrinsic commercialvalue or merit. However, if a characteristic that is of commercial value or merit satisfies all thecriteria for inclusion it may be considered in the normal way.
5.2.3 The characteristics included in the individual Specific Guidelines are not necessarily exhaustiveand may be expanded with additional characteristics if that proves to be useful and the characteris-tics meet the conditions set out above.
5.3 States of Expression of CharacteristicsTo enable varieties to be tested and a variety description to be established, the range of expression of
each characteristic in the Specific Guidelines is divided into a number of states for the purpose of de-scription, and the wording of each state is attributed a numerical “Note.” The division into states ofexpression is influenced by the type of expression of the characteristic. Where appropriate examplevarieties are provided in the Specific Guidelines to clarify the states of expression of a characteristic onthe patterns of UPOV and the Indian procedure has been adequately harmonized.
5.4 Types of Expression of CharacteristicsTo enable the appropriate use of characteristics in DUS testing, it is important to understand the
different ways in which characteristics can be expressed. The following section identifies the differenttypes of expression and considers their application in DUS testing.
5.4.1 Qualitative Characteristics“Qualitative characteristics” are those that are expressed in discontinuous states [e.g. sex of plant:
dioecious female (1), dioecious male (2), monoecious unisexual (3), monoecious hermaphrodite (4)].Thesestates are self-explanatory and independently meaningful. All states are necessary to describe the fullrange of the characteristic, and every form of expression can be described by a single state. The order ofstates is not important. As a rule, the characteristics are not influenced by environment.
5.4.2 Quantitative Characteristics“Quantitative characteristics” are those where the expression covers the full range of variation from
one extreme to the other. The expression can be recorded on a one-dimensional, continuous or discrete,linear scale. The range of expression is divided into a number of states for the purpose of description[e.g. length of stem: very short (1), short (3), medium (5), long (7), very long (9)]. The division seeks toprovide, as far as is practical, an even distribution across the scale. The Specific Guidelines do notspecify the difference needed for distinctiveness. The states of expression should, however, be meaningfulfor DUS assessment.
Plant Variety Journal of India 133
5.4.3 Pseudo-Qualitative CharacteristicsIn the case of “pseudo-qualitative characteristics,” the range of expression is at least partly continuous,
but varies in more than one dimension (e.g. shape: ovate (1), elliptic (2), circular (3), obviate (4) andcannot be adequately described by just defining two ends of a linear range. In a similar way to qualitative(discontinuous) characteristics – hence the term “pseudo-qualitative” – each individual state of expressionneeds to be identified to adequately describe the range of the characteristic.
5.5 Observation of Characteristics5.5.1 Trial Design
Where possible and useful, recommendations are given in the Specific Guidelines for plot size,sample size, number of replications and the number of independent growing cycles in order thatcomparable and reliable results may be obtained by the various members.
5.5.2 Bulk SamplesIf it is necessary to examine characteristics in the form of bulk samples, specific guidance is provided
in this document.
5.6 Special Characteristics5.6.1 Characteristics Expressed in Response to External Factors
Characteristics based the response to external factors, such as living organisms (e.g. disease resistancecharacteristics) or chemicals (e.g. herbicide resistance characteristics), may be used provided that theyfulfill the criteria specified in section 5.2. In addition, because of the potential for variation in suchfactors, it is important for those characteristics to be well defined and an appropriate method establishedwhich will ensure consistency in the examination.
5.6.2 Chemical ConstituentsCharacteristics based on chemical constituents may be accepted provided they fulfill the criteria
specified in section 5.2. It is important for those characteristics to be well defined and an appropriatemethod established for examination. A separate consultant group is being chartered to define and identifythe protocols for special characters.
5.6.3 Combined Characteristics5.6.3.1 A combined characteristic is a simple combination of a small number of characteristics. Provided
the combination is biologically meaningful, characteristics that are assessed separately maysubsequently be combined, for example the ratio of length to width, to produce such a combinedcharacteristic. Combined characteristics must be examined for distinctiveness, uniformity and stabilityto the same extent as other characteristics. In some cases, these combined characteristics are examinedby means of techniques, such as Image Analysis.
5.6.3.2 Combined characteristics are not to be confused with the application of methods, such as“multivariate analysis”. The potential for use of multivariate analysis is considered useful in suchcases.
5.7 New Types of CharacteristicsThe use of new types of characteristics, including the possible use of molecular characteristics, will
be considered in due course of time or wherever appropriate.
134 Volume 1, No. 1
5.8 Functional Categorization of Characteristics5.8.1 Grouping characteristics
These are characteristics that can be universally used for grouping the varieties. These are sufficientlyindependent of environmental influences in all regions. Level of expression of these characteristics willbe sufficient for establishing distinctiveness. Grouping characteristics can be of qualitative, quantitativeor pseudo-qualitative types, which provide useful discrimination among the varieties of commonknowledge from documented states of expression recorded at different locations. Such characteristicsshould be asterisked characteristics and should be included in Technical Questionnaire. Recorded statesof expression of these characteristics are used to select varieties of reference collection that can beexcluded from growing trial for testing of distinctiveness. Grouping characteristics can be used, eitherindividually or in combination with other such characteristics to organize the growing trial so that thesimilar varieties are grouped together.
5.8.2 Asterisked characteristicsThese are characteristics that the experts consider important for DUS testing. These characteristics
should be used as a matter of routine for all varieties in every growing period. Such characteristicsshould always be included in variety description except when the regional environmental conditionsrender it impossible. They are marked with asterisk in the Specific Guidelines. A characteristic shouldonly receive an asterisk status if (a) it is important for description (b) it is needed as a minimum informationfor the exchange of information on the variety (c) all experts agree to asterisk (d) for a pest or diseaseresistance characteristics, where it has only “absent, present” states.
5.8.3 Standard characteristicsThere are a number of characteristics that are important but adequate information is not there on
their wide acceptability. Such characteristics have been accommodated without any asterisk.
5.8.4 Additional characteristicsNewly identified characteristics are called additional characteristics. However, these should satisfy
the criteria of characteristics for use in DUS testing. Such characteristics did not find place in theSpecific Guidelines developed initially but could be considered for inclusion in future. These facilitateharmonization in the development and use of new characteristics and provide opportunity for expertreview.
5.8.5 Supportive evidence characteristicsThese are characteristics that the authorities do not consider sufficient on their own to establish
distinctiveness but which may provide supporting evidence for other differences which then are used fordistinctiveness. They are not included in test guidelines, but if they meet certain requirements, are includedas an Annexure to Specific Guidelines with a special mention that they do not form part of the actualSpecific Guidelines. The characteristics are considered useful but not enough on their own to establishdistinctiveness. These are not used as routine characteristics but only at the request of applicant of thecandidate variety and only if a test procedure has been accepted by the competent authority. Supportingevidence characteristics should only be used as a complement to other differences in morphological orphysiological characteristics. For example, in case of electrophoresis, there has to be good knowledgeof genetic background, standard method and a positive result in a ring test method between Countriesproviding Plant Variety Protection. Use of electrophoresis as supportive evidence characteristic hasbeen incorporated in the UPOV Test Guidelines of wheat, maize, soybean and barley crops and PPV&FRA
Plant Variety Journal of India 135
is also developing guideline on this separately and a team of consultants have been drawn for thispurpose.
5.9 Special Characteristics5.9.1 Characteristics expressed in response to external factors: Some characteristics are expressed inresponse to certain external factors viz., disease resistance characteristics and chemical resistancecharacteristics. It is important that these characteristics are well defined and an appropriate method isavailable to ensure consistency in examination.
5.9.2 Chemical constituents’ characteristics:
Characteristics based on chemical constituents may be used for DUS testing provided they fulfill thecriteria and an appropriate method for examination is available.
5.9.3 Combined characteristics that are assessed separately, but have a clearly biological connection,may subsequently be combined, for examples the ratio of length to width. Combined characteristicsmust be examined for distinctiveness, uniformity and stability to the same extent as othercharacteristics.
5.10 Recording of colour characteristicsExaminer of DUS test is usually required to record the observations on colour characteristics of
plant parts such as seedling, leaf petal, seed etc. Since each colour manifests several shades, recording ofprecise colour and shade becomes confusing. It is, therefore, recommended that Royal HorticulturalSociety (RHS) Colour Charts should be used while recording colour characteristics. The following listexplains the grouping of RHS Colour charts by colour groups. (Example)
1 White: 155A, 155B, 155C, 155D, 157D
2 Yellow-green: 1B, 1C, 1D, 2C, 2D, 3D, 4C, 149A, 150A, 150B, 150C, 150D, 154A, 154B,154C, 154D
3 Light yellow: 4D, 5D, 6D, 8B, 8C, 8D, 9C, 9D, 10A, 10B, 10C, 10D, 11B, 11C, 12C, 12D,13D,14D, 15D, 16D
4 Yellow: 1A, 2A, 2B, 3A, 3B, 3C, 4A, 4B, 5A, 5B, 5C, 6A,6B, 7B, 7C, 7D,8A, 9A, 9B, 12A,12B
5 Yellow-orange: 11A, 13A, 13B, 13C, 14A, 14B, 14C, 15A, 15B, 15C, 16A, 16B, 16C, 17A,17B, 17C, 17D, 18A, 19A, 20A, 20B, 21A, 21B, 21C, 22A, 23A, 23B
6. EXAMINING DISTINCTIVENESS
6.1 Requirements of the PPV&FR Act, 2001As per the PPV&FR Act, 2001, to satisfy the requirement of distinctiveness, a variety must be
clearly distinguishable from any other variety whose existence is a matter of common knowledge.
6.2 Varieties of Common KnowledgeKey aspects for determining whether a potential variety is, in fact, a variety and moreover, whether
its existence is a matter of common knowledge are set out below. These considerations apply equally toall types of variety, whether protected or not. A more detailed explanation of the issues related to variet-ies of common knowledge are to be as below.
136 Volume 1, No. 1
6.2.1 Criteria for a VarietyA variety whose existence is a matter of common knowledge must satisfy the definition of a variety
given under Section 2 (i) (iii) of the PPV&FRA, 2001 but this does not necessarily require fulfillment ofthe DUS criteria required for grant of a registration under the Act. If felt necessary using the provisionsunder sub section, such a test can be conducted by the Authority for reasons of getting a clearly distin-guishable character.
6.2.2 Common Knowledge6.2.2.1 Specific aspects which should be considered to establish common knowledge include, among
others:
a) Commercialization of propagating or harvested material of the variety, or publishing a detaileddescription;
b) The filing of an application for the grant of a breeder’s right or for the entering of a variety in anofficial register of varieties, under PPV&FR Act, 2001 which is deemed to render that variety amatter of common knowledge from the date of the application, provided that the application leads tothe grant of a breeder’s right or to the entering of the variety in the official register of varieties, as thecase may be;
c) Existence of living plant material in publicly accessible plant collections.
6.3 Clearly Distinguishing a New Variety
6.3.1 Comparing Varieties
6.3.1.1 It is necessary to examine distinctiveness in relation to all varieties of common knowledge.However, a systematic individual comparison may not be required with all varieties of commonknowledge. For example, where a candidate variety is sufficiently different, in the expression of itscharacteristics, to ensure that it is distinct from a particular group (or groups) of varieties of com-mon knowledge, it would not be necessary for a systematic individual comparison with the varietiesin that group (or those groups).
6.3.1.2 In addition, certain supplementary procedures may be developed to avoid the need for a system-atic individual comparison. For example, the publication of variety descriptions, inviting commentfrom interested parties, or cooperation between states of the Indian Union, in the form of an ex-change of technical information, could be considered as supplementary procedures. However, suchan approach would only be possible where the supplementary procedures, in conjunction with theother procedures, provide an effective examination of distinctiveness overall. Such procedures mayalso be appropriate for consideration of varieties of common knowledge, for which living plantmaterial is known to exist (see section 5.2.2) but where, for practical reasons, material is not readilyaccessible for examination.
6.3.1.3 Wherever a candidate variety can be distinguished in a reliable way from varieties of commonknowledge, by comparing documented descriptions, it is not necessary to include those varieties ofcommon knowledge in a growing trial with the respective candidate variety. Where there is nopossibility of clearly distinguishing them from the candidate variety, the varieties should be com-pared with the candidate variety in a growing trial or other appropriate test. This harmonization ofvariety descriptions is required in minimizing the work load of the DUS examiner.
Plant Variety Journal of India 137
6.3.1.4 To help in the process of examining varieties, certain information is requested from the breeder,usually through a Technical Questionnaire to be submitted with the application. The model Techni-cal Questionnaire, included in the Test Guidelines, seeks information on specific characteristics ofimportance for distinguishing varieties, information on the breeding scheme of the variety and anyother information, which may help to distinguish the variety. It also requests the breeder to identifysimilar varieties and characteristics by which the candidate may be distinguished from these similarvarieties.
6.3.2 Clearly Distinguishing Varieties Using CharacteristicsThe basis for using characteristics in the examination of distinctiveness is explained in Chapter 3,
section 3.4.
6.3.2.1 Truly qualitative characteristics: Truly qualitative characteristics are those that show discretediscontinuous states with no arbitrary limits. These are recorded on a one dimensional scale andshow discontinuous variation from one extreme to the other. They are divided into a number ofstates of expression for the purpose of description. These characteristics are not influenced by theenvironment. There are not many true qualitative characteristics.
Examples:Plant: sex Dioecious female (1); Dioecious male (2); Monoecious unisexual
(3); Monoecious hermaphrodite (4)
Flower: number of whorls one (1), two (2), three (3)
6.3.2.2 Pseudo-qualitative characteristics: These are qualitative characteristics of which the range ofexpression is at least partly continuous varying in more than one dimension. These characteristicscannot be defined just by two ends of linear range as in the case of to disregard continuous variationfor practical purpose and the states created are meaningful and sufficiently different from each other.
Examples:Shape : ovate (1), elliptic (2), round (3), obviate (4)
Expression : absent or very weakly expressed (1), weakly expressed (2),strongly expressed (3)
6.3.2.3 Quantitative characteristics: These are the characteristics, which are expressed on a one-dimen-sional scale and exhibit continuous variation from one extreme to the other. The expressed can berecorded on a one-dimensional, continuous or discrete, linear scale. They are divided in to a numberof states of expressions for the purpose of descriptions. The guidelines do not specify the differenceneeded for distinctiveness. The whole range of variation of a character is divided into nine states,which are normally equally spaced and measured on one-dimensional scale. Some truly quantitativecharacteristics may be handled as qualitative when only condensed range is used instead of fullrange of nine states.
Examples: Intensity of anthocyanin coloration: full range – absent or very weak (1), very weak to weak(2), weak (3), weak to medium (4), medium (5), medium to strong (6), strong (7), strong to very strong(8), very strong (9)
6.3.3 The Criteria for Distinctiveness Using CharacteristicsThe Act does not elaborate the term “clearly distinguishable.” However, in order to provide some
138 Volume 1, No. 1
guidance on the interpretation of the term, the following basis has been developed for the use of charac-teristics to clearly distinguish varieties. A variety may be considered to be clearly distinguishable if thedifference in characteristics is:
(a) Consistent, and (b) Clear
6.3.3.1 Consistent Differences
6.3.3.1.1 One means of ensuring that a difference in a characteristic, observed in a growing trial, issufficiently consistent is to examine the characteristic on at least two independent occasions. Thiscan be achieved in both annual and perennial varieties by observations made on plantings in twodifferent seasons or, in the case of other perennial varieties, by observations made in two differentseasons after a single planting. Guidance on the possible use of other approaches, such as twodifferent environments in the same year, is explored.
6.3.3.1.2 However, in some circumstances the influence of the environment is not such that a secondgrowing cycle is required to provide assurance that the differences observed between varieties aresufficiently consistent. For example, if the growing conditions of the crop are controlled, such as ina greenhouse with regulated temperature and light, it may not be necessary to observe two growingyears. In addition, the differences observed between varieties could be so clear that a repeated grow-ing cycle may not be necessary. In both these circumstances, the features of propagation of thevariety and the quality of the plant material will need to be taken into account. In other words, theuniformity and stability of the material should be highly convincing to the examiner.
6.3.3.1.3 The individual Specific Guidelines specify whether several independent growing cycles arerequired to show sufficient consistency, or whether, for certain species, the growing test could bereduced or increased.
6.3.3.2 Clear Differences
Determining whether a difference between two varieties is clear depends on many factors, andshould consider, in particular, the type of expression of the characteristic (Chapter 5, section 5.4) beingexamined, i.e. whether it is expressed in a qualitative, quantitative, or pseudo-qualitative manner.
6.3.3.2.1 Truly Qualitative Characteristics
In truly qualitative characteristics, the difference between two varieties may be considered clear ifone or more characteristics have expressions that fall into two different states in the Specific Guidelines.Varieties should not be considered distinct for a qualitative characteristic if they have the same state ofexpression.
6.3.3.2.2 Quantitative Characteristics
Quantitative characteristics are considered for distinctiveness according to the method of observationand the features of propagation of the variety concerned.
6.3.3.2.3 Pseudo-Qualitative Characteristics
A different state in the Specific Guidelines may not be sufficient to establish distinctiveness (Section5.3). However, in certain circumstances, varieties described by the same state of expression may beclearly distinguishable.
Plant Variety Journal of India 139
6.4 Use of Parental Formula for Distinctiveness in Hybrid VarietiesThe possible use of parental formulae in the examination of DUS of hybrid varieties is one approach.
If distinctiveness is not apparent in the hybrid, but parental lines are different, then a laboratory basedtest for distinctiveness can be considered as ‘special characteristics’.
6.5 Level of UniformityA difference only in the level of uniformity of a characteristic, without any resultant change in the
overall expression of the characteristic in the variety, is not a basis for establishing distinctiveness.
6.6 Interpretation of Observations for the Assessment of Distinctiveness without theApplication of Statistical Methods
6.6.1 In cases where there is very little variation within varieties, the determination of distinctiveness isusually on the basis of a visual assessment, rather than by statistical methods.
6.6.2 For qualitative characteristics, the difference between two varieties may be considered clear if oneor more characteristics have expressions that fall into two different states in the Specific Guidelines.
6.6.3 For quantitative characteristics, a difference of two Notes often represents a clear difference, butthat is not an absolute standard for assessment of distinctiveness. Depending on factors, such as thetesting place, the year, environmental variation or range of expression in the variety collection, aclear difference may be more or less than two ‘Note’.
6.6.4 In the case of pseudo-qualitative characteristics, guidance for the interpretation of observationsfor the assessment of distinctiveness without the application of statistical methods has been providedin document listed in Annexure – II.
6.6.5 If the application of statistics is needed to assess distinctiveness, further guidance can be found indocument ‘statistical technique useful in DUS testing cited in Annexure II.
6.7 Interpretation of Observations for the Assessment of Distinctiveness with theApplication of Statistical Methods
6.7.1 General
6.7.1.1 For measured characteristics as well as for visually assessed characteristics statistical methodscan be applied. Appropriate methods have to be chosen for the interpretation of observations. Thedata structure and the type of scale from a statistical point of view (nominal, ordinal, interval orratio) are decisive for the choice of appropriate methods. The data structure depends on the methodof assessment (visual assessment or measurements, observation of plots or single plants), which isinfluenced by the type of characteristic, the features of propagation of the variety, the experimentaldesign and other factors. DUS examiners should be aware of certain basic rules of statistics andespecially the fact that their use is linked to mathematical assumptions and the use of experimentaldesign practices, such as randomization. Therefore, those assumptions should be verified beforeapplying statistical methods. Some statistical methods are quite robust, however, and can be used,with some caution, even if some assumptions are not fully met.
6.7.1.2 Document “Statistical Techniques useful in DUS testing” by NBPGR 2005 provides guidanceon some appropriate statistical procedures for DUS assessment and includes keys for the choice ofmethods in relation to the data structure.
140 Volume 1, No. 1
6.7.1.3 A combined characteristic should only be used for distinctiveness if the uniformity criteria forthe combined characteristic itself, and not only its components, have been satisfied.
6.7.2 Visually Assessed CharacteristicsNon-parametric statistics may be used when visually assessed characteristics have been recorded on
a scale that does not fulfill the assumptions of the usual parametric statistics. The calculation of themean value, for example, is only permitted if the Notes are taken on a graded scale, which shows equalintervals throughout the scale. In the case of non-parametric procedures, the use of a scale that has beenestablished on the basis of example varieties representative of the different states of the characteristics isrecommended. The same variety should then always receive about the same Note and thereby facilitatethe interpretation of data. More details on the handling of visually assessed characteristics are beingdeveloped and will be standardized.
6.7.2.1 Qualitative Characteristics
For visually assessed qualitative characteristics, different states of expression in direct comparisonsare generally sufficient to assess distinctiveness. In most cases, therefore, no statistical methods areneeded for the interpretation of the results.
6.7.2.2 Quantitative Characteristics
6.7.2.2.1 Quantitative characteristics are not necessarily assessed by measuring or counting and can beassessed visually. Where there is doubt regarding the use of a normally visually assessed quantita-tive characteristic as the distinguishing characteristic in relation to another variety, it should bemeasured and quantified if that is possible with reasonable effort.
6.7.2.2.2 A direct comparison between two similar varieties is always recommended, since direct pairwise comparisons are the most reliable. In each comparison, a difference between two varieties isacceptable as soon as it can be assessed visually and could be measured, although such measure-ment might be impractical or require unreasonable effort.
6.7.2.2.3 The simplest case for establishing distinctiveness is when clear differences between varieties,in pair-wise comparisons, are of the same sign, provided these differences can be expected to recurin subsequent trials (e.g. variety A is consistently and sufficiently greater than B) and there are asufficient number of comparisons. However, in most cases, establishing confidence that varietiesare clearly distinguishable is more complex. This will be explained further in a document that isbeing drafted.
6.7.2.3 Pseudo-Qualitative Characteristics
The use of statistics for the assessment of pseudo-qualitative characteristics depends on the indi-vidual case, and no general recommendation can be made.
6.7.3 Measured CharacteristicsThe following paragraphs provide guidance on the typical methods for examining distinctiveness
according to the particular features of propagation of the variety:
6.7.3.1 Self-Pollinated and Vegetative Propagated Varieties
Several statistical methods for the handling of measured quantitative characteristics are alreadyavailable. One method established for self-pollinated and vegetative propagated varieties is that variet-ies can be considered clearly distinguishable if the difference between two varieties equals or exceeds
Plant Variety Journal of India 141
the Least Significant Difference (LSD) at a specified probability level with the same sign over an appro-priate period, even if they are described by the same state of expression. This method is appropriate forself-pollinated and vegetative propagated varieties because the level of variation within such varieties isrelatively low.
6.7.3.2 Cross-Pollinated Varieties
6.7.3.2.1 COYD and Refined COYD
UPOV has developed a method known as the Combined Over Years Distinctiveness (COYD) analy-sis, which takes into account variations between years. Its main use is for cross-pollinated, includingsynthetic varieties but, if desired, it can also be used for self-pollinated and vegetative propagated vari-eties in certain circumstances. This method requires the size of the differences to be sufficiently consis-tent over the years and takes into account the variation between years. It is explained further in document“Statistical techniques useful in DUS testing” published by the NBPGR in 2005 (see Annexure – II).
A refinement to the COYD analysis, which is also provided, should be used to adjust the COYDanalysis when environmental conditions cause a significant change in the spacing between varietiesmeans in a year, such as when a late spring causes the convergence of heading dates. It is supplementedby a further LSD method for cases where few varieties in the growing tests lead to less than about 20degrees of freedom for the estimation of standard error.
Where COYD analysis cannot be used because the statistical criteria are not fulfilled, non-paramet-ric procedures can be considered.
7. EXAMINING UNIFORMITY
7.1 Requirements of the Act, 2001.According to The PPV&FR Act Article 15 (3) (c), a material is uniform, subject to variation that
may be expected from the particular features of its propagation, it is sufficiently uniform in its essentialcharacteristics. Thus it is clear what characteristics are the bases for examination of uniformity.
7.2 Relevant CharacteristicsAt least for the purposes of the PPV&FR Act 2001, it is necessary to clarify the meaning of relevant
characteristics. Relevant characteristics of a variety include at least all characteristics used for the ex-amination of DUS or included in the variety description established on the date of grant of protection ofthat variety. Therefore, any obvious characteristic may be considered relevant, irrespective of whether itappears in the Specific Guidelines or not.
7.3 Level of Uniformity According to the Particular Features of PropagationThe uniformity requirement for a variety is linked to the particular features of its propagation. This
means that the level of uniformity required for truly self-pollinated varieties, mainly self-pollinatedvarieties, inbred lines of hybrid varieties, vegetatively propagated varieties, cross-pollinated varieties,mainly cross-pollinated varieties, synthetic varieties, composites, multilines and hybrid varieties will, ingeneral, be different. Being logical, the PPV&FR Authority agrees to these procedural details of uniformity.
7.4 Methods for the Examination of UniformityWhere all the plants of a variety are very similar, and in particular for vegetatively propagated and
self-pollinated varieties, it is possible to assess uniformity by the number of obviously different plants –
142 Volume 1, No. 1
“off-types” – that occur. However, where the range of variation within a variety is larger, because of thefeatures of its propagation, and in particular for cross-pollinated, including synthetic, varieties, the plantsare not all very similar and it is not possible to visualize which plants should be considered as atypical or“off-types.” In this case the uniformity can be assessed by considering the overall range of variation,observed across all the individual plants, to determine whether it is similar to comparable varieties.These two general approaches as generally followed by UPOV and adopted by PPV&FR Authority foruse in India are explained below:
7.4.1 Self -Pollinated and Vegetatively Propagated Varieties
7.4.1.1 Determination of Off-Types by Visual Assessment
A plant is to be considered an off-type if it can be clearly distinguished from the variety in theexpression of any characteristic of the whole or part of the plant that is used in the testing of distinctive-ness, taking into consideration the particular features of its propagation. This definition makes it clearthat, in the assessment of uniformity, the standard for distinctiveness between off-types and a candidatevariety is the same as for distinctiveness between a candidate variety and other varieties.
7.4.1.2 Determination of Off-Types Using Measurements
Most characteristics of self-pollinated and vegetative propagated varieties are observed visually, orby making a single measurement in a group of plants. However, the level of acceptance to call it uniformshall very and has been given in crop specific guideline.
7.4.1.3 Statistical Basis for Setting Numbers of Off-TypesThe acceptable number of off-types tolerated in samples of various sizes is often based on a fixed
“population standard” and “acceptance probability.” The “population standard” can be expressed as thepercentage of off-types to be accepted if all individuals of the variety could be examined. The probabil-ity of correctly accepting that a variety is uniform is called the “acceptance probability.” Based on statis-tical calculations for “population standards” and “acceptance probabilities,” the recommended “popula-tion standard” and “acceptance probability” are stated in the individual Specific Guidelines. The Spe-cific Guidelines also recommend the maximum number of off-types tolerated for a given sample size.
7.4.1.3.1 Mainly Self-pollinated Varieties and Inbred Lines of Hybrid Varieties
For the purpose of DUS testing, mainly self-pollinated varieties are those that are not fully self-pollinated but are treated as self-pollinated for testing. For these, as well as for inbred lines of hybridvarieties, a higher tolerance of off-types can be accepted, compared to truly self-pollinated and vegeta-tive propagated varieties. For individual species/situation the population standard will be prescribed.
7.4.2 Cross-Pollinated VarietiesCross-pollinated varieties, including mainly cross-pollinated and synthetic varieties, generally ex-
hibit wider variations within the variety than vegetative propagated or self-pollinated varieties and in-bred lines of hybrid varieties, and it is more difficult to determine off-types. Therefore, relative tolerancelimits, for the range of variation, are set by comparison with comparable varieties, or types, alreadyknown. This means that the candidate variety should not be significantly less uniform than the compa-rable varieties.
7.4.2.1 Visually Observed Characteristics
For characteristics that are recorded by visual observation of single plants, the acceptable level of
Plant Variety Journal of India 143
variation for the variety should not significantly exceed the level of variation found in comparablevarieties already known.
7.4.2.2 Measured Characteristics
For measured characteristics, the acceptable level of variation for the variety should not signifi-cantly exceed the level of variation found in comparable varieties already known. UPOV has proposedseveral statistical methods for dealing with uniformity in measured quantitative characteristics and manyare covered in the statistical techniques useful in DUS testing of NBPGR 2005. One method, whichtakes into account variations between years, is the Combined Over Years Uniformity (COYU) method.The Authority will do the analysis for listed DUS parameters that are measured characters.
7.4.3 Assessment of Uniformity in Hybrid Varieties
7.4.3.1 General
7.4.3.1.1 The assessment of uniformity in hybrid varieties depends on the type of hybrid, i.e. whether itis a single-cross hybrid or another type, and whether it is a hybrid resulting from inbred parent lines,vegetatively propagated lines, or from cross-pollinated parents.
7.4.3.1.2 The uniformity and stability of a hybrid variety may be assessed by examining the uniformityand stability of the hybrid itself or, under certain conditions, that of the progenitors and the hybrid.
7.4.3.2 Single- Cross Hybrid Varieties Resulting from Inbred Parent Lines
Single-cross hybrid varieties resulting from inbred lines are treated as mainly self-pollinated variet-ies. However, an additional tolerance is allowed for the occurrence of self-pollinated inbred parentplants. It is not possible to fix a percentage, as decisions differ according to the species and the methodof propagation. However, the percentage of such plants should not be so high as to interfere with thetrials. Where appropriate, a maximum number will be set in the Specific Guidelines.
7.4.3.3 Single- Cross Hybrid Varieties Not Resulting Exclusively from Inbred Parent Lines
For hybrid varieties resulting from at least one cross-pollinated parent, relative tolerance limitsshould be used, and they should be treated as cross-pollinated or synthetic varieties as long as no otherproof is given.
7.4.3.4 Multiple-Cross Hybrid Varieties
7.4.3.4.1 For other than single-cross hybrids (e.g. three-way crosses or double crosses), a segregation ofcertain characteristics is acceptable if it is compatible with the method of propagation of the variety.Therefore, if the heredity of a clear-cut segregating characteristic is known, it is required to behavein the predicted manner. If the heredity of the characteristic is not known, it is treated in the sameway as other characteristics in cross-pollinated varieties, i.e. relative tolerance limits, for the rangeof variation, are set by comparison with comparable varieties, or types, already known.
7.4.3.4.2 For setting a tolerance for the occurrence of self-pollinated parent plants, the same consider-ations apply as for a single-cross hybrid variety.
7.5 Unrelated and Very Atypical PlantsThe test material may contain plants that are very atypical or unrelated to those of the variety. These
are not necessarily treated as off-types, or part of the variety, and may be disregarded, and the test may becontinued, as long as the removal of these very atypical or unrelated plants does not result in an insuffi-
144 Volume 1, No. 1
cient number of suitable plants for the examination, or make the examination impractical. In choosingthe term “may be disregarded,” it is clear that it will depend on the judgment of the crop expert. Inpractice, in tests conducted with a small number of plants, just one single plant could interfere with thetest, and therefore should not be disregarded. The field population size if not disturbed by this Atypicalplant (Rogue or another plant species) then an impartial assessment can be made.
8. EXAMINING STABILITY8.1 Requirements of the PPV&FR Act, 2001
Section 15 (3) (d) of the Act says that a variety is stable “if its essential characteristics remainunchanged after repeated propagation or, in the case of a particular cycle of propagation, at the end ofeach cycle”.
8.2 Relevant / Essential CharacteristicsThe relevant or essential characteristics include at least all characteristics used for the examination
of DUS or included in the variety description established at the date of grant of protection of that variety.Therefore, all obvious characteristics may be considered, irrespective of whether they appear in the TestGuidelines or not.
8.3 Methods for the Examination of Stability
8.3.1 General
8.3.1.1 In practice, it is not usual to perform tests of stability that produce results as certain as those ofthe testing of distinctiveness and uniformity. However, experience has demonstrated that, for manytypes of variety, when a variety has been shown to be uniform, it can also be considered to be stable.Furthermore, if the variety is not stable, material produced will not conform to the characteristics ofthe variety, and where the breeder is unable to provide material conforming to the characteristics ofthe variety, the breeder’s right may be cancelled.
8.3.1.2 Where appropriate, or in cases of doubt, stability may be tested, either by growing a furthergeneration, or by testing a new seed or plant stock to ensure that it exhibits the same characteristicsas those shown by the previous material supplied. Further, guidance on the examination of stabilityis considered and would be drafted.
8.3.2 Hybrid VarietiesThe stability of a hybrid variety may, in addition to an examination of the hybrid variety itself, also
be assessed by examination of the uniformity and stability of its parent lines, if so demanded.
9. COMPOSITION OF TEST GUIDELINES9.1 Coverage of Individual Specific Guidelines
In most cases, individual Specific Guidelines are prepared for each species. Although, in somecases, it may be appropriate to prepare Specific Guidelines covering a wider or narrower grouping ofvarieties. Different groups of varieties within a species can be dealt with in separate or subdividedSpecific Guidelines, if the categories can be reliably separated on the basis of characteristics suitable fordistinctiveness, or where an appropriate procedure has been developed to ensure that all varieties ofcommon knowledge will be adequately considered for distinctiveness.
Plant Variety Journal of India 145

152 Volume 1, No. 1
measurement and observation without prejudicing the observations on the standing plants until theend of the growing period. Each test shall include about 2500 plants, in the plot size and plantingspace specified below across three replications. Separate plots for observation and for measurementcan only be used if they have been subjected to similar environmental conditions. All the replicationsshall be sharing similar environmental conditions of the test location.
4. Test plot design
Number of rows : 30
Row length : 6 m
Row to row distance : 30 cm
Plant to plant distance : 20 cm
Expected plants / replications : 900
Number of replications : 3 (irrigated and shallow lowland tests)
: 5 (upland, saline-alkaline, semi-deep)water and deep water tests.
5. Observations shall not be recorded on plants in border rows.
6. Additional test protocol for special purpose shall be established by the PPV & FR Authority.
IV. Methods and observations
1. The characteristics described in the Table of characteristics (see section VII) shall be used for thetesting of varieties, inbred lines and hybrids for their DUS.
2. For the assessment of Distinctiveness and Stability observations shall be made on 30 plants or partsof 30 plants, which shall be equally divided among 3 replications (10 plants per replication).
3. For the assessment of Uniformity of characteristics on the plot as a whole (visual assessment by asingle observation of a group of plants or parts of plants), a population standard of 0.1% with anacceptance probability of at least 95% shall be applied. In the case of a sample size of 1500 plantsthe number of off-types shall not exceed 4.
4. For the assessment of Uniformity of characteristics on single panicle-rows, plants or parts of plants(visual assessment by observations of a number of individual panicle-rows, plants or parts of plants)the number of aberrant panicle-rows, plants or parts of plants shall not exceed 2 in 50.
5. For the assessment of all colour characteristics, the latest Royal Horticultural Society (RHS) colourchart shall be used.
6. Unless otherwise indicated, all observations on the leaf shall be made on the penultimate leaf.
V. Grouping of varieties
1. The candidate varieties for DUS testing shall be divided into groups to facilitate the assessment ofDistinctiveness. Characteristics, which are known from experience not to vary, or to vary only slightlywithin a variety and which in their various states are fairly evenly distributed across all varieties inthe collection are suitable for grouping purpose.
Plant Variety Journal of India 153
2. The following characteristics are proposed to be used for grouping rice varieties:
a) Basal leaf: Sheath colour (Characteristic 2)
b) Time of heading (50% of plants with panicles) (Characteristic 20)
c) Stem: Length (excluding panicle; excluding floating rice) (Characteristic 29)
d) Decorticated grain: Length (Characteristic 54)e) Decorticated grain: Shape (in lateral view) (Characteristic 56)
f) Decorticated grain: Colour (Characteristic 57)
g) Endosperm: Content of amylose (Characteristic 59)
h) Decorticated grain: Aroma (Characteristic 62)
VI. Characteristics and symbols1. To assess Distinctiveness, Uniformity and Stability, the characteristics and their states as given in
the Table of characteristics (Section VII) shall be used.
2. Note (1 to 9) shall be used to describe the state of each character for the purpose of digital dataprocessing.
3. Legend:
(*) Characteristics that shall be observed during every growing season on all varieties and shallalways be included in the description of the variety, except when the state of expression of any ofthese characters is rendered impossible by a preceding phenological characteristic or by theenvironmental conditions of the testing region. Under such exceptional situation, adequate explanationshall be provided.
(+) See Explanation on the Table of characteristics in Section VIII. It is to be noted that for certaincharacteristics, the plant parts on which observations to be taken are given in the explanation orfigure(s) for clarity and not the colour variation.
4. A decimal code number in the sixth column of Table of characteristics indicates the optimum stagefor the observation of each characteristic during the growth and development of plant. The relevantgrowth stages corresponding to these decimal code numbers are described below:
Decimal Code for the Growth Stages
10 After germination, emergence of first leaf through coleoptile/second leaf visible (less than 1 cm)
40 Booting : the increase in the size of the young panicle and its inward extension inside the upper leafsheaths detectable as a bulge in the rapidly elongating culm
50 1st spikelet of inflorescence just visible
55 ½ of inflorescence emerged
60 Beginning of anthesis : it begins with the protrusion of the first dehiscing anthers in the terminalspikelets on the panicle branches
65 Anthesis half way
70 Milk development stage: formation of white milky sap within the spikelets.
80 Dough development (spikelets become hard)
90 Ripening (terminal spikelets ripened)
92 Caryopsis hard (can be no longer be dented by thumb nail and over 90% spikelets ripened)

Characteristic 56: Decorticated grain: Shape (in lateral view)
After dehusking (brown rice) or after milling (polished rice) the length and breadthof the grains are measured for computing the shape and size. Select minimum 10 fullgrains per replication with both the ends intact and measure the length and breadth byusing Grain Shape Tester or Dial Micrometer. Average of their measurements are takenin millimeters and length/breadth ratio is calculated. Ramaiah, 1969 classification isused to assign the grain shape based on length and length / breadth ratio.
As referred in Rice Research in India: ICAR Publication, 1985.
State Kernel length (mm) Length/breadth ratio Note
Short Slender < 6.0 > 3.0 1
Short Bold < 6.0 < 2.5 2
Medium Slender < 6.0 2.5-3.0 3
Long Bold > 6.0 < 3.0 5
Long Slender > 6.0 > 3.0 4
Basmati type > 6.61 > 3.0 5
Extra Long Slender > 7.5 > 3.0 6
Characteristic 58: Endosperm: Presence of amylose
By observation glutinous rice has waxy grains and non-glutinous rice has non-waxy to transparentwith various grades according to the amylose content of the endosperm. When it is necessary glutinousrice and rice with various grades of amylose content, chemical analysis is needed.
Characteristic 59: Endosperm: Content of amylose
The simplified procedure of Juliano (1971) is used for the amylose content analysis. Twenty whole-grain milled rice is ground in a UDY cyclone mill (sieve mesh size 60). 100 mg of rice powder is put intoa 100 ml volumetric flask and 1 ml of 95% ethanol and 9 ml of 1N Sodium hydroxide are added. Thecontents are heated on a boiling water bath to gelatinize the starch. After cooling for one hour, distilledwater is added and contents are mixed well. For each set of samples run, low, intermediate and highamylose standard varieties are included to serve as checks. Five ml of the starch solution is put in a 100ml volumetric flask with a pipette. One ml of 1 N acetic acid, 2 ml of iodine solution (0.2 g iodine and2.0 g potassium iodide in 100 ml of aqueous solution) is added and volume is made up with distilledwater. Contents are shaken well and let stand for 20 minutes. Absorbance of the solution is measuredat 620 nm with a spectrophotometer of standard make. Amylose content is determined by using aconversion factor and the results are expressed on a dry weight basis. The moisture content of the sampleis essentially constant and need not be determined if the relative humidity and temperature of the laboratoryis controlled.
Note : The classification of extra long slender grain is done according to SES, IRRI 1996; for Basmati type long slender grain length shallbe more than 6.61 mm as per the proceedings of Annual Rice Workshop, 1998.

Characteristic 60: Polished grain: Expression of white core (Varieties with endosperm of amyloseabsent only)
Degree of chalkiness describes the milled of rice sample with respect to (a) white core (b) whitebelly and (c) white back. Chalky white spots often appear in the starchy endosperm. A white chalkyregion extending to the edge of the ventral side and towards the centre of the endosperm is called a whitecore. Soft textured, white spots occurring in the middle part on the ventral side (side on which theembryo lies) are called abdominal white or white belly. A long white streak on the dorsal side is calledthe white back.

Characteristic 61: Gelatinization temperature
Gelatinization temperature through alkali spreading and clearing test (Little et. al., 1958)
Duplicate sets of six whole milled grains are spaced evenly in transparent plastic boxes (50 mm x 42mm x 22 mm) containing 10 ml of 1.7% Potassium Hydroxide. The dishes are kept at 27-30oC for 23hours undisturbed in an incubator. Standard varieties must be used as checks for high, intermediate andlow gelatinization temperature. The spreading of kernels noted on a 7 point scale is expressed as averageof six values. Scoring is done as follows:
Alkali spreading Value / Scale
1. Kernel not affected
2. Kernel swollen
3. Kernel swollen, collar incomplete and narrow
4. Kernel swollen, collar complete and wide
5. Kernel split or segmented, collar complete
6. Kernel dispersed, merging with collar
7. All kernel dispersed and intermingled

Characteristic 62: Decorticated grain: Aroma
The method consists of adding about 15 ml of water to 5g of rice sample in a test tube (200 mm x 35mm), soak for 10 minutes. Cook the sample in the water bath for 15 minutes. Transfer the cooked rice into a petri dish. After cooling keep it in the refrigerator for 20 minutes. Then the petri plates are openedand the contents are smelled. The samples possessing the scent, as one could easily feel, produce a sharpand readily recognizable aroma. (DRR, unpublished).

These test guidelines shall apply to all varieties, hybrids and parental lines of Bread wheat (Triticumaestivum L.)
II. Seed material required
1. The Protection of Plant Varieties and Farmers’ Rights Authority (PPV & FRA) shall decide whereand in what quantity and quality of the seed material are required for testing a variety denominationapplied for registration under the Protection of Plant Variety and Farmers’ Rights (PPV & FR) Act,2001. Applicants submitting such seed material from a country other than India shall make sure thatall customs and quarantine requirements stipulated under relevant national legislations and regulationsare complied with. The minimum quantity of the seed to be provided by the applicant shall be 3000gram in the case of the candidate variety or hybrid and 1500 gram for each of the parental line of thehybrid. Each of these seed lots shall be packed and sealed in ten equal weighing packets and submittedin one lot. Wherever, individual spikes are to be supplied, such spikes shall be individually packedand submitted along with the said seed lot.
2. At least 100 ears, each representing the normal ear size and drawn from the main tiller of the candidatevariety shall be submitted.
3. The seeds and ears submitted shall have at least 95 % germination, 98% physical purity, highestgenetic purity, uniformity, sanitary and phyto-sanitary standards. In addition the moisture content ofthe seed shall not exceed 8 - 9% to meet the safe storage requirement. The applicant shall alsosubmit along with the seed a certified data on germination test made not more than one month priorto the date of submission.
4. The seed material shall not have been subjected to any chemical and bio-physical treatment.
III. Conduct of tests
1. The minimum duration of the DUS tests shall normally be at least two independent similar growingseasons.
2. The test shall normally be conducted at least at two test locations. If any essential characteristics ofthe candidate variety are not expressed for visual observation at these locations, the variety shall beconsidered for further examination at another appropriate test site or under special test protocol onexpressed request of the applicant.
3. The field tests shall be carried out under conditions favouring normal growth and expression of alltest characteristics. The size of the plots shall be such that plants or parts of plants could be removedfor measurement and observation without prejudicing the other observations on the standing plantsuntil the end of the growing period. Each test shall include about 1000 plants, in the plot size andplanting space specified below across three replications. Separate plots for observation and formeasuring can only be used if they have been subjected to similar environmental conditions. All thereplications shall be sharing similar environmental conditions of the test location.

I. Subject
These test guidelines shall apply to all varieties, hybrids and parental lines of Chickpea (Cicerarietinum L.)
II. Seed material required
1. The Protection of Plant Varieties and Farmers’ Rights Authority (PPV & FRA) shall decide when,where and in what quantity and quality of the seed material are required for testing a varietydenomination applied for registration under the Protection of Plant Variety and Farmers’ Rights(PPV& FR) Act, 2001. Applicants submitting such seed material from a country other than Indiashall make sure that all customs and quarantine requirements stipulated under relevant nationallegislations and regulations are complied with. The minimum quantity of the seed to be provided bythe applicant shall be 3000 gram in the case of Kabuli type and 2000 gram for Desi type of thecandidate variety. Each of these seed lots shall be packed and sealed in ten equal weighing packetsand submitted in one lot.
2. The seed submitted shall have at least 95 % germination, 98% physical purity, highest genetic purity,uniformity, sanitary and phyto-sanitary standards. In addition the moisture content of the seed shallnot exceed 8 - 9% to meet the safe storage requirement. The applicant shall also submit along withthe seed a certified data on germination test made not more than one month prior to the date ofsubmission.
3. The seed material shall not have been subjected to any chemical or bio-physical treatment.
III. Conduct of tests
1. The minimum duration of the DUS tests shall normally be at least two independent similar growingseasons.
2. The test shall normally be conducted at least at two test locations. If any essential characteristics ofthe candidate variety are not expressed for visual observation at these locations, the variety shall beconsidered for further examination at another appropriate test site or under special test protocol onexpressed request of the applicant.
3. The field tests shall be carried out under conditions favouring normal growth and expression of alltest characteristics. The size of the plots shall be such that plants or parts of plants could be removedfor measurement and observation without prejudicing the other observations on the standing plantsuntil the end of the growing period. Each test shall include about 500 plants, in the plot size andplanting space specified below across three replications. Separate plots for observation andmeasurement can only be used if they have been subjected to similar environmental conditions. Allthe replications shall be sharing similar environmental conditions of the test location.
4. Test plot design
Number of rows : 8
Row length : 5 m
212 Volume 1, No. 1
Row to row distance : 45 cm

Expected plants/replication : 200
Number of replications : 3
5. Observations shall not be recorded on plants in border rows.
6. Additional test protocols for special purpose shall be established by the PPV & FR Authority.
IV. Methods and observations
1. The characteristics described in the Table of characteristics (see section VII) shall be used for thetesting of varieties, inbred lines and hybrids for their DUS.
2. For the assessment of Distinctiveness and Stability, observations shall be made on 30 plants or partsof 30 plants, which shall be divided among 3 replications (10 plants in each replication).
3. For the assessment of Uniformity of characteristics on the plot as a whole (visual assessment by asingle observation of a group of plants or parts of plants), a population standard of 1% with anacceptance probability of at least 95% shall be applied. In the case of a sample size of 100 plants, thenumber of off-types shall not exceed 3.
4. For the assessment of all colour characteristics, the latest Royal Horticultural Society (RHS) colourchart shall be used.
V. Grouping of varieties
1. The candidate varieties for DUS testing shall be divided into groups to facilitate the assessment ofDistinctiveness. Characteristics, which are known from experience not to vary, or to vary only slightlywithin a variety and which in their various states are fairly evenly distributed across all varieties inthe collection are suitable for grouping purposes.
2. The following characteristics are proposed to be used for grouping Chickpea varieties:
a) Time of flowering (Characteristic 3)
b) Flower : Colour (Characteristic 9 )
c) Seed: Colour (Characteristic 15 )
d) Seed : Size (Characteristic 16 )
VI. Characteristics and symbols
1. To assess Distinctiveness, Uniformity and Stability, the characteristics and their states as given inthe Table of characteristics (Section VII) shall be used.
2. Note (1 to 9) shall be used to describe the state of each character for the purpose of digital dataprocessing.
3. Legend:
(*) Characteristics that shall be observed during every growing period on all varieties and shall alwaysbe included in the description of the variety, except when the state of expression of any of these

FIELD PEA (Pisum sativum L.)
I. Subject
These test guidelines shall apply to all varieties, hybrids and parental lines of Field pea (Pisumsativum L.).
II. Seed material required
1. The Protection of Plant Varieties and Farmers’ Rights Authority (PPV & FRA) shall decide when,where and in what quantity and quality of the seed material are required for testing a varietydenomination applied for registration under the Protection of Plant Variety and Farmers’ Rights(PPV & FR) Act, 2001. Applicants submitting such seed material from a country other than Indiashall make sure that all customs and quarantine requirements stipulated under relevant nationallegislations and regulations are complied with. The minimum quantity of the seed to be provided bythe applicant shall be 2000 gram in the case of the candidate variety. Each of these seed lots shall bepacked and sealed in ten equal weighing packets and submitted in one lot.
2. The seed submitted shall have at least 85% germination, 98% physical purity, highest genetic purity,uniformity, sanitary and phyto-sanitary standards. In addition the moisture content of the seed shallnot exceed 8 - 9% to meet the safe storage requirement. The applicant shall also submit along withthe seed a certified data on germination test made not more than one month prior to the date ofsubmission.
3. The seed material shall not have been subjected to any chemical or bio-physical treatment.
III. Conduct of tests
1. The minimum duration of the DUS tests shall normally be at least two independent similar growingseasons.
2. The test shall normally be conducted at least at two test locations. If any essential characteristics ofthe candidate variety are not expressed for visual observation at these locations, the variety shall beconsidered for further examination at another appropriate test site or under special test protocol onexpressed request of the applicant.
3. The field tests shall be carried out under conditions favouring normal growth and expression of alltest characteristics. The size of the plots shall be such that plants or parts of plants could be removedfor measurement and observation without prejudicing the other observations on the standing plantsuntil the end of the growing period. Each test shall include about 350 plants, in the plot size andplanting space specified below across three replications. Separate plots for observation andmeasurement can only be used if they have been subjected to similar environmental conditions. Allthe replications shall be sharing similar environmental conditions of the test location.
4. Test plot design:
Number of rows : 5
Row length : 5 m
Plant Variety Journal of India 241
Row to row distance : 60 cm (determinate types)
90 cm (indeterminate types)
Plant to plant distance : 20 cm
Expected plants / replication : 125
Number of replications : 3
5. Observations shall not be recorded on plants in border rows.
6. Additional test protocols for special purpose shall be established by the PPV & FR Authority.
IV. Methods and observations
1. The characteristics described in the Table of characteristics (see section VII) shall be used for thetesting of varieties, inbred lines and hybrids for their DUS.
2. For the assessment of Distinctiveness and Stability, observations shall be made on 30 plants or partsof 30 plants, which shall be equally divided among 3 replications (10 plants per replication).
3. For the assessment of Uniformity of characteristics on the plot as a whole (visual assessment by asingle observation of a group of plants or parts of plants), a population standard of 0.5% with anacceptance probability of at least 95% shall be applied. In the case of a sample size of 300 plants, thenumber of off-types shall not exceed 4.
4. For the assessment of all colour characteristics, the latest Royal Horticultural Society (RHS) colourchart shall be used.
V. Grouping of varieties
1. The candidate varieties for DUS testing shall be divided into groups to facilitate the assessment ofDistinctiveness. Characteristics, which are known from experience not to vary, or to vary only slightlywithin a variety and which in their various states are fairly evenly distributed across all varieties inthe collection are suitable for grouping purposes.
2. The following characteristics are proposed to be used for grouping field pea varieties:
a) Plant : Height (Characteristic 14)
b) Stipule : Rabbit-eared stipules (Characteristic 6)
c) Flower : Opening (days) (Characteristic 8)
d) Pod : Shape of the distal part (Characteristic 12)
e) Seed : Cotyledon colour (Characteristic 17
f) Seed : Shape (Characteristic 15)
VI. Characteristics and symbols
1. To assess Distinctiveness, Uniformity and Stability, the characteristics and their states as given inthe Table of characteristics (Section VII) shall be used.
2. Note (1 to 9) shall be used to describe the state of each character for the purpose of digital dataprocessing.
