GCAP-GMP Projects
  • MasAgro: IMIC-LA + TTF
  • USDA-SAGARPA Highland Maize
  • HarvestPlus (Maize)
  • SIMLESA (Objectives 2 + 3)
  • CSISA (Maize component)
  • BMZ-Bangladesh
  • The Striga Project in Africa (IR maize + Agronomic management)
  • USAID-Mozambique
collaborative activities in la
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.

Characterizing field variability

Monitoring soil moisture



  • 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….

improved maize for african soils imas

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.












Major Rainfed Maize Cultivated States of India

>80% of the maize area in India is under rainfed condition

collaboration through csisa
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
Opportunities for strengthening GCAP-GMP collaboration
  • 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)
