Wheat Linked Topcross Population Information from the Seeds of Discovery - MasAgro Biodiversidad Project

Prashant Vikram Carolina Saint Pierre Thomas Payne Juan Burgueño Carolina Sansaloni (2017, [Dataset])

The Linked Topcross Population (LTP) was generated to introgress useful traits from wheat germplasm bank accessions, including synthetic hexaploids and landraces, into elite wheat varieties. In addition to generating pre-breeding materials selected for important traits such as heat and drought tolerance, this population has been used to generate data that can be useful for several applications, including genome-wide association studies.

CIMMYT Eastern Africa Maize Regional On-Station (Stage 4) and On-Farm (Stage 5) Trials: Results of the 2021 to 2022 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 Eastern Africa and similar agro-ecological zones. Following rigorous trialing and a stage-gate advancement process and culminating in the 2022 Eastern Africa Regional On-Farm Trials, CIMMYT has advanced a total of 6 new elite maize hybrids, each of which met the stringent performance criteria for CIMMYT’s eastern Africa early (EAPP1B), intermediate (EAPP1A) or late (EAPP2) maize breeding pipelines. 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 Eastern Africa under various management and environmental conditions.

Dataset on rhizosphere microbiota and yield of maize and barley in a field experiment with six seed treatments in the Central Highlands of Mexico

Pablo Jaramillo-López Marcela Sarabia Simon Fonteyne Abel Saldivia Tejeda Nele Verhulst Mette Vestergård John Larsen (2023, [Dataset])

Six seed treatments were tested for 2 growing cycles (summer of 2021 and 2022) in a field experiment with maize (Zea mays L.) and barley (Hordeum vulgare L.) under conservation agriculture in the Mexican highlands, at CIMMYT’s experiment station of El Batán Texcoco, the State of Mexico, Mexico. The experiment was a randomized complete block design with 3 replicates, with separate areas for maize and barley. The six seed treatments included a negative control, a chemical seed treatment (different for maize and barley, depending on common practices in the area), Trichoderma, Metarhizium, a commercial mixture of plant growth promoting rhizobacteria, and a combination of Trichoderma and Metarhizium. Soil and root samples were taken at two and three sampling times during the 2021 crop cycle for barley and maize, respectively. Yield and yield components were determined at the end of the crop cycle in 2021 and 2022. The soil and root samples were used to measure root growth (root biomass per core), root colonization with mycorrhizal fungi, root infection with pathogens (Polymyxa, Pythium, Microdochium), soil microbial communities in terms of biomarker fatty acids, and ecological guilds of soil nematodes (Bacterivores, fungivores, plant parasitic and predators).

21st High Temperature Wheat Yield Trial

Ravi Singh Carolina Saint Pierre (2023, [Dataset])

CIMMYT annually distributes improved germplasm developed by its researchers and partners in international nurseries trials and experiments. The High Temperature Wheat Yield Trial (HTWYT) is a replicated yield trial that contains spring bread wheat (Triticum aestivum) germplasm adapted to Mega-environment 1 (ME1) which represents high temperature areas.

Genealogical information for maize pre-breeding materials in the Seeds of Discovery-MasAgro Biodiversidad project: 2013-2015

Terence Molnar (2015, [Dataset])

This dataset contains pedigree information for the maize breeding materials generated through the Seeds of Discovery-Ma sAgro Biodiversidad project from 2013 through 2015. These tropical, subtropical and highland materials are being developed to introduce novel alleles for tar spot resistance, drought tolerance, and high-anthocyanin content into elite maize lines.
