Climate change has increased genotype-environment interactions in wheat breeding
(Research Square, 2020)
International Symposium on Wheat Yield Potential: Challenges to International Wheat Breeding
Like many other patterns, investment in research is often cyclical. International centers like CIMMYT have focused substantial resources on biotic and abiotic stresses for about two decades now, but raising total productivity ...
Genomic prediction with pedigree and genotype X environment interaction in spring wheat grown in South and West Asia, North Africa, and Mexico
(Genetics Society of America, 2017)
Developing genomic selection (GS) models is an important step in applying GS to accelerate the rate of genetic gain in grain yield in plant breeding. In this study, seven genomic prediction models under two cross-validation ...
Increasing yield potential in wheat: breaking the barriers. Proceedings of a workshop held in Ciudad Obregon, Sonora, Mexico
CIMMYT's focus on developing wheat varieties that produce higher and more stable yields has made a tremendous difference in the lives of millions of people in the developing world. In the mid 1960s, the dramatic increases ...
Results of the 1st International Heat Stress Genotype Experiment
Fischer (1989) summarized the detrimental effects of high temperature on wheat growth as follows: Yield reduction can occur at temperatures above a mean as low as 150C, with the spike and grain growth phases being especially ...
Adaptation of wheat to the canopy environment: physiological evidence that selection for vigor or random selection may reduce the frequency of high-yielding genotypes
Increasing the potential yield of wheat is a major thrust of CIMMYT's Wheat Program. Farmer's wheat yields are linearly related to the yield potential of new varieties. At the same time, breeders should ideally be able to ...
Genomic prediction of gene bank wheat landraces
(Genetics Society of America, 2016)
This study examines genomic prediction within 8416 Mexican landrace accessions and 2403 Iranian landrace accessions stored in gene banks. The Mexican and Iranian collections were evaluated in separate field trials, including ...
Pedigree-based prediction models with genotype × environment interaction in multi-environment trials of CIMMYT wheat
(Crop Science Society of America (CSSA), 2017)
Genotype × environment (G × E) interaction can be studied through multienvironment trials used to select wheat (Triticum aestivum L.) lines. We used spring wheat yield data from 136 international environments to evaluate ...
