Low soil nitrogen stress can contribute to food insecurity, malnutrition, and rural poverty in maize-dependent smallholder communities of sub-Saharan Africa (SSA). Enhanced selection for improved varieites may result from a better understanding of the genomic regions associated with low nitrogen tolerance. Four F3 maize populations were used to study the genetic architecture of grain yield (GY) and its associated traits (anthesis-silking interval (ASI), anthesis date (AD), plant height (PH), ear position (EPO), and ear height (EH)) under different soil nitrogen regimes in Kenya and Zimbabwe. Information about the populations and the genotypic data used in the analyses are provided in this dataset. The results of the analysis are reported in the related journal article.

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 Eastern Africa and similar agro-ecologies in other regions. Each year, CIMMYT’s Global Maize Program conducts regional on-station and on-farm hybrid maize trials through a network of NARS and private seed companies in eastern and southern Africa under various management and environmental conditions. Promising maize hybrids developed by the CIMMYT-Africa team, along with relevant checks from private seed companies and National Agricultural Research Programs, are included in these trials. Phenotypic data collected in Stage 4 and Stage 5 trials for the selected hybrids from Product Profile 1A (PP1A) as well as information about the trial sites and management and environmental conditions are provided in this dataset.

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 Southern Africa and similar agro-ecological zones. Following a rigorous trialing and a stage-gate advancement process culminating in the 2023 Stage 5 On-farm trials, CIMMYT advanced a total of three new elite maize hybrids in Southern Africa in 2023. 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 Southern Africa under various management and environmental conditions.
