CIMMYT is pleased to announce the release of a set of 26 new CIMMYT maize lines (CMLs). These CMLs were developed by the CIMMYT Global Maize Program’s multi-disciplinary teams of scientists at breeding locations in sub-Saharan Africa, Latin America and Asia. These lines are adapted to the tropical/subtropical maize production environments targeted by CIMMYT and partner institutions. CMLs are freely available to both public and private sector breeders worldwide under the standard material transfer agreement (SMTA).

CIMMYT seeks to develop improved maize inbred lines with superior performance and multiple stress tolerance to improve maize productivity for resource-constrained smallholder farmers. To achieve this aim, CMLs are released after intensive evaluation in hybrid combinations under various abiotic and biotic stresses. Suitability as either seed or pollen parent is also thoroughly evaluated.

Release of a CML does not guarantee high combining ability or per se performance in all environments; rather, it indicates that the line is promising or useful as a hybrid component or parent for pedigree breeding for one or more target mega-environments. The descriptions of the lines include heterotic group classification, along with information on their specific combining ability with widely-used CIMMYT lines.

Further details on all CMLs, including the pedigrees, are available here.

A limited quantity of seed of the CMLs can be obtained from the CIMMYT Germplasm Bank. To send a request, please contact Denise Costich, Head of the Maize Genetic Resources Center:
