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...

Phenotypic data collected in 2019 Stage 4 and 2020 Stage 5 trials for CIMMYT maize hybrid JH1104 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 Eastern Africa under various management and environmental conditions.

Dataset of daily fine particular matter (PM2.5) emissions for the period 2012 though 2020. Emissions were calculated from wheat and rice production statistics and active fires from the Visible Infrared Imaging Radiometer Suite (VIIRS) 375-m product. Rice harvest period was considered from October to November, and wheat harvest from April through May.

Data from two CIMMYT and KALRO household surveys representative of six maize production areas or agroecological zones in Kenya. The surveys were conducted in 2010 and 2013 collected data on farmer demographics, adoption of improved technologies and practices, marketing, access to agricultural information, and farmer adaptation to climate change.

The Stem Rust Resistance Screening Nursery is a single replicate nursery that contains diverse spring bread wheat (Triticum aestivum) germplasm adapted to all mega-environments with total 50-100 entries and white/red grain color.

CIMMYT develops and distributes elite tropical CIMMYT maize lines (CMLs) for use around the world. This dataset contains genotypic profiles for all 615 of the CML lines released by 2022 and fourteen temperate maize inbred lines. All lines were genotyped with 180 kompetitive allele-specific PCR (KASP) markers. These data were used to generate a reference...

Empirical studies of early generation genomic selection strategies for parental selection or population improvement are still lacking in wheat and other major crops. We show the potential of rapid-cycle recurrent GS to increase genetic gain for grain yield in wheat. We show a consistent realized genetic gain for grain yield after three cycles of...

This experiments were established with different rates of nitrogen in order to generate a wide range of values for NDVI and grain yield in order to develop a calibration model for the GreenSeeker in Sinaloa.

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 Latin America and similar agro-ecological zones. Following a rigorous trialing and a stage-gate advancement process culminating in...

In plant breeding, sparse testing methods have been suggested to improve the efficiency of the genomic selection methodology. The data provided in this dataset were used to evaluate four methods for allocating lines to environments for sparse testing in multi-environment trials. The analysis was conducted using a multi-trait and uni-trait framework. The...

This experiments were established with different rates of nitrogen in order to generate a wide range of values for NDVI and grain yield in order to develop a calibration model for the GreenSeeker in Oaxaca.

This experiments were established with different rates of nitrogen in order to generate a wide range of values for NDVI and grain yield in order to develop a calibration model for the GreenSeeker in Yaqui Valley.

The Fusarium Head Blight Screening Nursery (earlier Scab Resistance Screening Nursery - SRSN) is a single replicate nursery that contains diverse spring bread wheat (Triticum aestivum) germplasm adapted to ME2 (High rainfall environment) and ME4 (Low rainfall, semi-arid environment) with total 50-100 entries and white/red grain color.

Soil sampling with 1x1 km grid in the agricultural area of the Chamic Municipality at at 0 to 30 cm depth.

Soil sampling with 1x1 km grid in the agricultural area of the Villacorzo and Concordia Municipalities at at 0 to 30 cm depth.

Soil sampling with 1x1 km grid in the agricultural area of the Pedro Escobedo and San Juan del Rio Municipalities at at 0 to 30 cm depth.

Soil sampling with 1x1 km grid in the agricultural area of the Huanimaro and Celaya Municipalities at at 0 to 30 cm depth.

International Durum Yield Nurseries (IDYN) are replicated yield trials designed to measure the yield potential and adaptation of superior CIMMYT-bred spring durum wheat germplasm that have been developed from tests conducted under irrigation and induced stressed cropping conditions in northwest Mexico. These materials have been subjected to numerous...

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 Latin America and similar agro-ecological zones. Following a rigorous trialing and a stage-gate advancement process culminating in...

This file contains the data from a survey conducted with 122 respondents, found drying maize in open air along the roads in the towns and urban centers of major maize growing areas of Kenya (Bungoma, Trans Nzoia, Uasin Gishu and Nakuru) and Nairobi. Most of them were maize traders, but there were also some farmers and a few millers. They were interviewed...
