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...

International Durum Screening Nursery (IDSN) distributes diverse CIMMYT-bred spring durum wheat germplasm adapted to irrigated and variable moisture stressed environments. Disease resistance and high industrial pasta quality are essential traits possessed in this germplasm. It is distributed to 100 locations, and contains 150 entries.

The Harvest Plus Advanced Nursery (HPAN) contains spring bread wheat (Triticum aestivum) germplasm adapted to ME1 (Optimally Irrigated, low rainfall environment) and ME5 (Warmer area environment) environments. It has 100-200 entries with a single replication, white grain color and distributed to more than 35 locations.

In sub-Saharan Africa, maize is a staple crop but yields remain sub-optimal. A novel hybrid seed technology offers the opportunity to reduce seed production costs and increase yields. This dataset contains data from on-farm and on-station trials collected in 2017 to 2019 in South Africa, Kenya and Zimbabwe to assess this hybrid seed production technology....

This dataset include data from a national wheat survey in Ehiopia in 2016 during the main season for a DNA fingerprinting study. The data contain wheat varieties genotyped using DNA fingerprinting (DNA FP), farmers recall survey and matching of DNA FP with farmers recall.

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

Conservation agriculture (CA) is based on minimal tillage, permanent soil cover and crop diversification. The data in this study were collected in a field trial network established to adapt CA to Mexico’s diverse cropping systems and local conditions. Soil health was studied in 20 trials with maize (Zea mays L.) in acro-ecologies ranging from handplanted...

Genetic architecture of grain yield (GY) has been extensively investigated in wheat using genome wide association study (GWAS) approach. However, most studies have used small panel sizes in combination with large genotypic data, typical examples of the so-called ‘large p small n’ or ‘short-fat data’ problem. Further, use of bi-allelic SNPs accentuated...

Conducted genome-wide association scan (GWAS) and explored the possibility of applying genomic prediction (GP) for Anther Extrusion (AE) in the CIMMYT hybrid wheat breeding program

CIMMYT and its network of collaborators in Mexico, conducted a series of experiments across agroecological zones of Mexico in 2017 and 2018 to evaluate the effect of different storage technologies on postharvest losses of maize. Experiments were conducted under “controlled” (i.e., managed by researchers) and “non-controlled” conditions (i.e., on-farm...

The Stem Rust Resistance Screening Nursery (STEMRRSN) 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.

The genotypic data included in this dataset were generated using DArTseq by the SAGA genotyping laboratory in Mexico. The dataset contains 8,154 SNPs on candidate varieties from Kazakhstan and those released by CIMMYT-ICARDA-IWWIP program. These were evaluated for tan spot resistance at Kazakhstan.

The Karnal Bunt Screening Nursery is a single replicate nursery that contains diverse spring bread wheat (Triticum aestivum) germplasm adapted to ME1 (Optimally irrigated, low rainfall environment) with total 50-100 entries and white/red grain color.

Agronomic systems based on zero tillage and residue retention are becoming more important due to their potential for climate change adaptation through the reduction of soil erosion and improved water availability. Genotype by tillage interactions for yield are not well understood and it is unknown whether tillage should be an evaluation factor in breeding...

CIMMYT’s durum wheat breeding program performed parallel selection in conventional tilled (CT) and zero tillage (ZT) soils with the aim to compare the effect of selection under either CT or ZT on the performance of selected progenies. From 16 initial crosses, 234 lines were selected under CT and 250 under ZT. All 484 lines were subsequently tested for...
