GCAP-GMP Projects● MasAgro: IMIC-LA + TTF● USDA-SAGARPA Highland Maize● HarvestPlus (Maize)● SIMLESA (Objectives 2 + 3)● CSISA (Maize component)● BMZ-Bangladesh● ICAR-QPM● The Striga Project in Africa (IR maize +

Agronomic management)● USAID-Mozambique

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

Linkages between IMIC-LA and TTF under MasAgro

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.

Monitoring soil moisture

● 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.

Soil and Climatic Scenarios of Maize Rainfed Soil and Climatic Scenarios of Maize Rainfed Areas in IndiaAreas in India

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)
