Five new CIMMYT maize hybrids available from the Latin America breeding program


CIMMYT is happy to announce five new, improved tropical and subtropical maize hybrids that are now available for uptake by public and private sector partners, especially those interested in marketing or disseminating hybrid maize seed across Latin America and similar agro-ecologies in other regions. NARES and seed companies are hereby invited to apply for licenses to pursue national release, scale-up seed production, and deliver these maize hybrids to farming communities.

The newly available CIMMYT maize hybrids were identified through rigorous, years-long trialing and a stage-gate advancement process which culminated in the 03-22LTHTWM4M, 04-22LTHTYM4M, 01-22MASTCHSTW and 02-22MASTCHSTY Stage 5 Trials. The products were found to meet the stringent performance and farmer acceptance criteria for CIMMYT’s breeding pipelines that are designed to generate products tailored in particular for smallholder farmers in stress-prone agroecologies of Latin America.
