A multi-stage sampling was employed to identify households. In the first stage 9 districts (five form Oromyia region, three from SNNP region and one from Benshangul region) were selected purposely. Accordingly, Bako Tibe, Gubuesyo, Shalla, Dudga, Adami Tullu, Mesrak Badawacho, Meskan, Hawassa Zuriya and Pawe selected. As the program focused on maize based...

The Adoption Pathways project was part of a portfolio of projects that has contributed to the broader theme of sustainable intensification research led by the International Maize and Wheat Improvement Center (CIMMYT) and made possible by the contribution of several teams from national and international research groups brought together by funding from the...

Cycle1 formed by inter mating selected S2 families genotypes genotyped with 84 SNPs for GEBV estimation for grain yield

This tutorial explains how to use the IWIN-DAP, which is an Add-In to Microsoft Excel 2010, to analyze data from CIMMYT’s International Wheat Information System. IWIN-DAP is an illustration of an alternative, quick and easy approach allowing the use of Excel to analyze multi-location trials from CIMMYT international nurseries. This tutorial explains, step...

Turkish landraces were genotyped using GBS and phenotyped for grain yield and yield component traits and stripe rust resistance at three locations. The data was used for a genome wide association study and important marker-trait associations were identified.

The International Bread Wheat Screening Nursery (IBWSN) is designed to rapidly assess a large number of advanced generation (F3-F7) lines of spring bread wheat under Mega-environment 1 (ME1) which represents diversity for a wide range of latitudes, climates, daylengths, fertility conditions, water management, and (most importantly) disease conditions. The...

Increases in genetic gains in grain yield can be accelerated through genomic selection (GS). In the present study seven genomic prediction models under two cross validation scenarios were evaluated on the Wheat Association Mapping Initiative population of 287 advanced elite lines phenotyped for grain yield (GY), thousand grain weight (GW), grain number...

The phenomenon of genotype × environment (G×E) interaction in plant breeding decreases selection accuracy, thereby negatively affecting genetic gains. Several genomic prediction models incorporating G×E have been recently developed and used in genomic selection of plant breeding programs. Genomic prediction models for assessing multi-environment G×E are...

Phenotypic data were collected in on-station field trials for advanced breeding lines from the CIMMYT Bread Wheat breeding program over several years.

Genetic profiling of wheat breeding lines from the CIMMYT bread wheat breeding program was carried out over several years.

Vegetation indices (VI) generated by using some bands from hyperspectral cameras are used as predictors of primary traits. This study proposes models that use all available bands as predictors of primary traits. The proposed models were ordinal least square (OLS), Bayes B, principal components with Bayes B, functional B-spline, functional Fourier and...

This study provides the genotypic results for a BC2F1 population screened with seven markers associated with heat tolerance-related QTL.

Summary results and individual trial results from the International Late Yellow Hybrid - ILYH, (Mid-altitude / Subtropical Three Way Crosses Yellow Hybrids, with High Concentrations of Provitamins A (especially beta-carotene) - CHTSPROA) conducted in 2012.

Summary results and individual trial results from the International Late Yellow Hybrid - ILYH, (Elite TropicalLate Yellow Normal and QPM Hybrid Trial Version A - CHTTY-A) conducted in 2012.

When plant scientists record information on multiple genotypes evaluated in multiple environments, a multi-environment single trait for assessing genotype × environment interaction (G×E) model is usually employed. Comprehensive models that simultaneously take into account the correlated traits and trait × genotype × environment interaction (T×G×E) are...
