Collaborative Activities in LA● Evaluation of yield trials under CA for USDA-
SAGARPA Highland Maize (1000 rows) and H+ (400 rows)
● Evaluation of advanced hybrids under CA in different TTF hubs under MasAgro.
● In 2011 under MasAgro, 2.5 ha planted under isolations for seed production of elite hybrids under CA, a collaboration between IMIC and TTF.
● Replenishing soil health at Tlalti Experimental Station

Rehabilitating Tlalti Field Station● As a result of historical land
management (and perhaps bad soils) the available good land at Tlatizapan is becoming increasing limited.
● Leaving the field bare and erosion over many years has resulted in areas of low and high fertility
● Station committee provided a formal structure for interaction with GCAP on improving Tlati. Bram, Pat and Ken offered a great deal of advice and on-site visits to recommend more sustainable land use and rehabilitation of soils.

● Good informal collaboration between Mexico based-GCAP group and GMP (particularly Bram, Nele and Ivan) on use and maintenance of NDVI, field variability, shovelomics….

• Scaling-up breeding for NUE• Increasing the capacity of the ARC, KARI,
and CIMMYT to select elite maize hybrids and OPVs under low-N conditions
• Applying DNA marker-assisted recurrent selection (MARS)
• Mobilizing single high impact genes.
• Fertilizer management designed for high-NUE varieties
• Fertilizer rates and timings optimized for IMAS hybrids and OPVs
Improved Maize for African Soils (IMAS)

Achieving sustainable Striga control in Africa● IITA is the lead center● Developing IR-maize and
evaluating Striga-resistant varieties in Kenya (Dan)
● Testing and deployment of IR-maize technology and integrated Striga control options in Kenya (Fred)
● The Striga project will test elite germplasm in multilocation trials and recommend suitable crop management options to DTMA.

Collaboration through CSISA Develop high-yielding, heat-tolerant, & disease- resistant maize
inbred lines and hybrids for current and future cereal & mixed crop-livestock systems
Experiments on maize under different management options undertaken through CSISA for identifying the best-bet maize varieties under rainfed conditions (ML Jat) – Significant G x M effects
Need for suitable production technology for early maize and full season maize

GCAP scientists are open to collaboration and happy to assist – how can we further strengthen the quality of our interactions● Better understanding of ongoing work/projects within each
program (e.g. low N)● Regular feedback on performance of genetic materials under CA
practices, especially on large plot evaluations● Validation of elite hybrids/varieties under CA in different regional
hubs● Evaluation of different agronomic practices for seed production● Effect of planting date, plant density and genotype on maize yield,
especially with new genetic materials coming out of breeding pipeline.
● On-farm trials in collaboration with national partners

Opportunities for strengthening GCAP-GMP collaboration● MAIZE CRP● CSISA – Phase II● Great scope for seeking joint
funding to build on the success of DTMA and IMAS, looking at management options for drought & low N, especially in SSA
● Mobilizing resources in a coordinated manner (e.g., SIMLEZa)
● Enhancing the impact of CIMMYT’s work in Eastern Asia (China) and SE Asia (Indonesia, Vietnam & Philippines)
