CIMMYT-Asia Maize Regional On-Station (Stage 4) and On-Farm (Stage 5) Trials: Results of the 2022-2023 Seasons and Product Announcement

New and improved maize hybrids, developed by the CIMMYT Global Maize Program, are available for uptake by public and private sector partners, especially those interested in marketing or disseminating hybrid maize seed across tropical regions of South Asia and similar agro-ecologies in other regions.. Following a rigorous trialing and a stage-gate advancement process culminating in the 2023 Stage 5 trials, CIMMYT advanced a total of six new elite maize hybrids in Asia in 2024 across the SADHT, SAWLDT, and SADT product profiles. Phenotypic data collected in Stage 4 and Stage 5 trials for the selected hybrids as well as information about the trial sites are provided in this dataset. These trials were conducted through a network of partners, including NARES and private seed companies, in Asia, under various management and environmental conditions.
