The world faces the challenge of growing more maize, responsibly and sustainably.

CIMMYT collaborates with national agricultural research institutions, non-government and community-based organizations, seed sector organizations, regional research networks, other CGIAR centers, private companies, and advanced research institutions to tackle the problem on a global scale by providing farmers the best seed, agronomy, and information needed to increase yields.

  • Provide diverse, high-yielding maize varieties that withstand infertile soils, drought, pests, and diseases.

  • Conduct research to help farmers exploit the full potential of improved seed while conserving soil and water resources.

  • Explore new market opportunities for small farmers.

  • Provide training opportunities in maize breeding and crop management research.


Update: CIMMYT maize inbred lines and pre-commercial hybrids with potential resistance to maize lethal necrosis (MLN)

Update: CIMMYT maize inbred lines and pre-commercial hybrids with potential resistance to maize lethal necrosis (MLN)
A CIMMYT-KARI MLN Screening Facility was established at Naivasha in September 2013, and a large array of maize germplasm is presently being evaluated against the disease under artificial inoculation. Subsequent to the development of effective protocols, CIMMYT and KARI have been conducting MLN screening trials in Kenya since 2012, to identify promising inbred lines and pre-commercial maize hybrids with resistance to MLN.

CIMMYT releases 22 new maize inbred lines for the tropics and subtropics

CIMMYT releases 22 new maize inbred lines for the tropics and subtropics

CIMMYT is pleased to announce the release of 22 new CIMMYT maize lines (CMLs). The CMLs were developed at various breeding locations of CIMMYT Global Maize Program by multi-disciplinary teams of scientists. These lines are adapted to the tropical/subtropical maize production environments targeted by CIMMYT and the partner institutions. CMLs are freely available to both public and private sector breeders worldwide under CIMMYT’s standard material transfer agreement (SMTA).

CIMMYT scientists have been working closely with virology experts from USDA-ARS and Kenya Agricultural Research Institute (KARI) to develop suitable protocols for testing the responses of maize germplasm against MLN, and to identify promising inbred lines and hybrids with resistance to MLN.  During the 2012-2013 crop season, the CIMMYT-KARI team undertook extensive screening of inbred lines, pre-commercial and commercial hybrids in Naivasha and Narok in Kenya, under high natural disease pressure and artificial inoculation, respectively.

Far in the South and seeking food security: East Timor farmers adopt improved maize seed

Far in the South and seeking food security: East Timor farmers adopt improved maize seed

Through five years of on-farm trials supported by the governments of East Timor and Australia using locally-suited crop varieties provided by five centers of the CGIAR-Consortium, small-scale farmers in East Timor learned about and acquired seed of improved varieties of maize and other key food crops, as well as improved cropping practices. The hungry season for the major staple, maize, was significantly reduced among the adopters and, with more recent support from the "Seed of Life" project and East Timor's Ministry of Agriculture and Fisheries, farming communities are producing improved maize seed to satisfy local demand.
