CIMMYT scientists develop improved maize and wheat lines, with resistance to globally important biotic and abiotic stresses, and with improved nutritional and processing quality. Our germplasm banks contain the largest and most diverse collections of maize and wheat in the world.
Improved and conserved seed is available to any research institution worldwide, and is distributed with compliance of the SMTA terms and conditions (FAQ). We collect data about the performance of our distributed lines for further improvement, and share conclusions with the international breeding and research community when available.
