The role of field gene banks in maintaining important horticultural

cultivars and improving its performance under desert

conditions

Dr. Wael Moussa GhaithResearcher in Boomology department

Field gene banks

• It is a type of field conservation of some horticultural species and cultivars which subjected to the optimum condition to preserve it as longer as possible.

Objectives of Field gene banks establishment

1) It is a cheap method for keeping important items of horticultural species and cultivars .

2) It is effective method to evaluate those cultivars under controlled conditions.

3) Studying the specific and interaction effects between those cultivars and the environmental conditions.

Objective of Field gene banks establishment

4. It serve as a certified center for supplying the farmers with important cultivars.

5. Applying many morphological, physiological, and genetic studies on many groups of cultivars in the same place and the same time.

6. Inserting those cultivars in some genetic development programs for improving their performance.

Models of Field gene bank in North Sinai research station

Olive cultivars field collection

• These field collection was cultivated in 1996 by many of cultivars such as Aswad Lybia, Itrana, Coratina, Techernuola, Bella di Spagna, Tanch, Manzanillo, Chiperssino, Karidalya, Nabali Saadeh, Jolit, Conservollia, Nabali Mohassan, Picholine, Jabaa, Douaibly, Mawi Abou Shoka, Sorany and Kaissy….

• Theses cultivars were obtained from ACSAD, and many other local cultivars were cultivated in the field gene bank.

• These cultivars act as propagation material to produce adapted seedlings for farmers.

• There are different morphological, physiological , and genetic evaluation studies were applied on these cultivars.

• Different parameters were studied to evaluate the olive field collection such as vegetative characteristics, flowering habit, blooming in relation to chilling, fruit physical and chemical characteristics and productivity.

Pomegranate cultivars field collection

• These cultivars are namely Wonderfull, Manfaloty, Nap El-Gaml, Saedy, Bany Rafea Morakab, Bany Rafea Ahmer, Wardy, Asutty, Banatty, Montakhab araby.

• These cultivars inserted in evaluation program under regulated Deficit irrigation treatments.

• These cultivars act as propagation material to produce adapted seedlings for farmers.

• Many of morphological, physiological , and genetic evaluation studies where applied on these cultivars.

Almond cultivars field collection

• There are different evaluation studies were applied on these cultivars in the field collection which named Non Pareil, Texas Mission, Peerless, IXL, Neplusultra, Jordanello, Jordans, drake, Eureke, Ivola.

• The selected Almond cultivars subjected to many of studies to solve the problem of self in-compatibility and cross in-compatibility to select the perfect group to obtain the best tree yield.

Almond cultivars field collection

• The selected Almond cultivars subjected to many of drought treatments in relation with many kinds of rootstocks such as Better Almond, Nemagard, Wildpeach, and Sweet almond.

• These cultivars act as propagation material to produce adapted seedlings for farmers.
