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 2022 Stage 5 trials, CIMMYT advanced a total of seven new elite maize hybrids in Southern Africa in 2022. 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.
Maize is increasingly being grown in the winter season in South Asia when there are low prevailing temperatures and frequent cold snaps. Therefore,.elite varieties must have cold resilience as an important trait. The current study identified a suite of genomic loci associated with grain yield along with agronomic traits such as flowering time and plant height under cold stress environments in a panel of advanced tropically adapted maize lines In addition, the study also identified four lines with potential cold resilience that could be used as breeding starts in the tropical maize breeding pipelines.
In 2004 and 2005 CIMMYT organized Regional Trials to evaluate early-maturing (EPOP05) and intermediate- to late-maturing (ILPOP05) open-pollinated varieties (OPVs) across eastern and Southern Africa. Phenotypic data are provided in this dataset. These trials were conducted through a network of partners, including NARS and private seed companies, in Southern and Eastern Africa under various management and environmental conditions.

Following a rigorous trialing and a stage-gate advancement process culminating in the 2020 Stage 5 trials, CIMMYT advanced a total of four new elite maize hybrids in Latin America in 2022 for Product Profile LA-PP1. These are yellow and white maize hybrids adapted for the tropical lowlands. Phenotypic data collected in Stage 4 and Stage 5 trials for the four 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 NARS and private seed companies, in Latin America under various management and environmental conditions. Nuevos y mejorados híbridos desarrollados por el Programa Global de Maíz del CIMMYT se ponen a disposición de instituciones del sector público y privado, especialmente para aquellas instituciones colaboradoras interesadas en la comercialización y diseminación de semilla de maíz en Latinoamérica o en zonas agroecológicas similares. Después de un riguroso proceso de evaluación de germoplasma en distintas etapas que culminó en ensayos de evaluación de híbridos en etapa cinco, el CIMMYT avanzó cuatro nuevos híbridos élite en Latinoamérica en 2022 por el Perfíl de Producto LA-PP1. Estos son híbridos amarillos y blancos adaptados a las tierras bajas tropicales. Datos fenotípicos recopilados en los ensayos en etapa cuatro y cinco por los cuatro hibridos avanzados, además de información sobre los sitios están incluidos en este conjunto de datos. Estos ensayos fueron conducidos bajo diferentes condiciones de manejo y ambientes a través de redes colaborativas con instituciones de investigación pública y empresas semilleras de Latinoamérica.
