Phenotyping for breeding and physiological pre-breeding
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 ...
Association mapping and nucleotide sequence variation in five drought tolerance candidate genes in spring wheat
(Crop Science Society of America, 2013)
Functional markers are needed for key genes involved in drought tolerance to improve selection for crop yield under moisture stress conditions. The objectives of this study were to (i) characterize five drought tolerance ...
Genome-wide association study for adaptation to agronomic plant density: a component of high yield potential in spring wheat
(Crop Science Society of America (CSSA), 2015)
Previous research has shown that progress in genetic yield potential is associated with adaptation to agronomic planting density, though its genetic basis has not been addressed before. In the current study, a wheat (Triticum ...
Stay-green in spring wheat can be determined by spectral reflectance measurements (normalized difference vegetation index) independently from phenology
(Oxford University Press; Society for Experimental Biology, 2012)
The green area displayed by a crop is a good indicator of its photosynthetic capacity, while chlorophyll retention or ?stay-green? is regarded as a key indicator of stress adaptation. Remote-sensing methods were tested to ...
Genome-wide comparative diversity uncovers multiple targets of selection for improvement in hexaploid wheat landraces and cultivars
(National Academy of Sciences, 2013)
Domesticated crops experience strong human-mediated selection aimed at developing high-yielding varieties adapted to local conditions. To detect regions of the wheat genome subject to selection during improvement, we ...
Modelling and genetic dissection of staygreen under heat stress
Plant chlorophyll retention—staygreen—is considered a valuable trait under heat stress. Five experiments with the Seri/Babax wheat mapping population were sown in Mexico under hot-irrigated environments. Normalized difference ...
