This dataset is built from a survey among wheat farming households in Bihar state. The survey was conducted by the International Maize and Wheat Improvement Center (CIMMYT) between August and September 2021. In total, the questionnaire was administered to 1,008 wheat-growing households. The survey elicited information on various topics, for example,...

A household survey was conducted from May to October 2018 in the Chüy, Issyk-Kul, and Osh oblasts of the Kyrgyz Republic. The dataset offers insights into production patterns, the socio-economic and demographic situations of farmers and households growing wheat, factors influencing their production decisions, the adoption of new wheat varieties, and the...

This dataset is derived from a study focused on developing an efficient method for arabinoxylan quantification, called PentoQuant. It includes phenotypic and molecular characterization data from 606 bread wheat samples developed through the spring bread wheat breeding program. The dataset comprises total and water-extractable arabinoxylan content values...

Gene-based marker data from international screening nurseries for marker-assisted selection

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...

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...

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).

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...

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.

The list includes wheat genotypes that have been evaluated for wheat blast resistance with data available publicly (database links are provided). The list is to be updated regularly

Wheat head blast index (%) data for seven CIMMYT nurseries (12HPAN, 13HLBSN, 13HZAN, 38SAWSN, 52IDSN, 53IBWSN, 54IBWSN) is presented. Field trials took place in Quirusillas and Okinawa (Bolivia) and Jashore (Bangladesh) during the 2022 cycles. Two sowings were made in each location/cycle.

Plant breediers must respond to the threats posed by climate change in order to help ensure global food security in the short and long term. A better understanding of the genetic underpinnings of heat tolerance can contribute to efforts to develop more resilient crops. The exome capture data from 149 spring wheat lines provided in this dataset were used...

Genomic prediction methods may be used to enhance efforts to rapidly introgress traits of interest from exotic germplasm into elite materials. This study examined the performance of different genomic prediction models using genotypic and phenotypic data related to 8416 Mexican landrace accessions and 2403 Iranian landrace accessions stored in germplasm...

This study provides supplemental data to support the study on Genomic Prediction of Resistance to Tan Spot, Spot Blotch and Septoria Nodorum Blotch on Synthetics Hexaploid Wheat.

The Green Revolution has led to intensive, irrigated rice-wheat systems across the Indo-Gangetic Plains (IGP). The limited turn-around time between rice harvest and sowing of the next crop (wheat) and mechanized harvesting of rice pose a critical challenge for farmers to sustainably handle the surplus rice residues. Because only a few economically viable...

The intensive, irrigated rice-wheat systems of the northwestern Indo-Gangetic Plains (NW IGP) are associated with the widespread burning of excess rice residue that cannot be otherwise disposed-off within the limited turn-around time. The second-generation direct seeders (SGDS) for wheat sowing, such as Happy Seeder, facilitate sowing under heavy stubble...

This survey was done in 122 villages of Punjab, as part of the SPIA-funded project on the impact of Conservation Agriculture (CA), particularly the impact of Happy Seeder technology, on yield and residue burning. During the exploratory surveys, we found that the adoption of CA depends on the soil structure. To identify the soil characteristics, our team...
