  1. GCAP-GMP Collaboration BM Prasanna GCAP Annual Meeting March 31, 2011 El Batan

  2. 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

  3. 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

  4. Linkages between IMIC-LA and TTF under MasAgro

  5. 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. Clear gradient in biomass of a maize hybrid in one block at Tlalti (NDVI measured 21 DAS)

  6. Improving the precision of drought & low N phenotyping Characterizing field variability Monitoring soil moisture Tlatizapan Ikenne • Soil measurements • conductivity (texture) • sampling • Biomass • NVDI • visual measurements • Yield Delta-T PR2 Probe Sentek Diviner 2000 Root phenotyping “shovelomics” • Good informal collaboration between Mexico based-GCAP group and GMP (particularly Bram, Nele and Ivan) on use and maintenance of NDVI, field variability, shovelomics…. J Lynch & S Trachsel

  7. 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)

  8. 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.

  9. 10 9 1 1 4 5 3 8 2 6 7 Major Rainfed Maize Cultivated States of India >80% of the maize area in India is under rainfed condition

  10. Soil and Climatic Scenarios of Maize Rainfed Areas in India

  11. 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

  12. 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

  13. 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)
