The dataset contains experimental data from the San Juan Cotzocon research platform in Oaxaca, Mexico. The database contains data on maize yield, management, profitability and phenology in relation to 8 evaluated treatments. The treatments differed in tillage (disk harrow, zero tillage or permanent raised beds), residue management (removing all or leaving...

The data were collected for the publication: "Does leaving crop residues in the field lead to greater frost damage in wheat and barley under conservation agriculture?" The dataset contains data from three experiments conducted to evaluate if leaving more residue in the field is associated with higher levels of frost damage. Farmers in the Bajio had...

New version of maize mega environments based upon new wordlclim 2.1 data. Based on Bellon et al. 2005 https://doi.org/10.1016/j.foodpol.2005.09.003 Supersedes previous version

Gray Leaf Spot (GLS) and Northern Corn Leaf Blight (NCLB) are two pathogens with high genetic diversity that can reduce grain yield in infected maize plants.To identify population-based quantitative trait loci (QTL) for GLS and NCLB resistance, a biparental population and an association mapping panel were genotyped and were also phenotyped across...

Maize post-flowering stalk rots (PFSR) are caused by at least six genera of fungal pathogens. They generally occur as a complex, along with secondary colonizers. PFSR are reported from all major maize growing ecologies and are expected to be exacerbated by the changing climates in Latin America, Asia, and Sub-Saharan Africa, A better understanding of the...

Genome-wide association study was performed in a Tunisian durum wheat collection. The collection was genotyped with the wheat 90K Illumina array and phenotyped for seportia tritici blotch.

A core collection of 235 durum wheat accessions consisting mainly of landraces was genotyped and evaluated for its genetic diversity and population structure. The same collection was phenotyped for the fungal pathogen Pyrenophora triciti-repentis (cause of tan spot disease of wheat) in Tunisia to perform genome-wide association analyses. The results...

This study provides supplemental data to support the study on Optimizing Genomic-Enabled Prediction: A Feature Weighting Approach for Enhancing within Family Accuracy.

Interspecific hybrids can be formed through allopolyploidization. Synthetic hexaploid wheats (SHW) have been created in breeding programs through the intentional crossing of tetraploid and diploid species. In this study, quantitative genetics tools developed to predict cross performance within a species were applied to predict the phenotypes of SHW for...

Maize stalk rot can cause significant economic losses for maize farmers around the world. Information on the genetic architecture of maize stalk rot could help breeders design effective breeding strategies to enhance resistance to stalk rot. This dataset was used to carry out genome-wide association analysis (GWAS) and genomic prediction for stalk rot in...

Lower yield of wheat in eastern India can be attributed to several input factors i.e., inappropriate crop management practices including other social and environmental factors. Among them, sub-optimal irrigation is one of the important factors. Recommended number of irrigations for optimal wheat harvest is 4-5 depending upon crop growth stages and...

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.

CIMMYT annually distributes improved germplasm developed by its researchers and partners in international nurseries trials and experiments. The High Rainfall Wheat Yield Trial (HRWYT) contains very top-yielding advance lines of spring bread wheat (Triticum aestivum) germplasm adapted to high rainfall, Wheat Mega-environment 2 (ME2HR).

Two types of experiments conducted in multi-location on-farm trials to evaluate the mechanized crop establishment methods (Drill-Direct Seeded Rice and Mechanical Transplanted Rice) alternative to traditional crop establishment methods (Manual transplanted rice and broadcasting followed by beushening) in three districts of Odisha over three years (2017 to...

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...

The Elite Selection Wheat Yield Trial (ESWYT) is a replicated yield trial that contains spring bread wheat (Triticum aestivum) germplasm adapted to Mega-environment 1 (ME1) which represents the optimally irrigated, low rainfall areas. Major stresses include leaf, stem and yellow rusts, Karnal bunt, and lodging. Representative areas include the Gangetic...

Maydis Leaf Blight (MLB) is a serious foliar disease for maize in warm and humid regions. The data in this dataset were used to investigate the genetic architecture underlying resistance to MLB using high resolution Genome Wide Association Studies and Genomic Prediction. A diverse panel of 336 maize inbreds adapted for the Asian tropics, were evaluated...

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...

GBS genotypic data for an Indian panel with 296 common wheat accessions.

DArTAG panel 2 validation data on 1454 CIMMYT spring bread wheat elite lines included in the 53, 54 and 55IWBWSN and 38, 39 and 40 SAWSN. DArTAG panel 2 consists of 3897 selected SNPs.
