TL;DR: The developed array and cluster identification algorithms provide an opportunity to infer detailed haplotype structure in polyploid wheat and will serve as an invaluable resource for diversity studies and investigating the genetic basis of trait variation in wheat.
Journal ArticleDOI
Genome-wide comparative diversity uncovers multiple targets of selection for improvement in hexaploid wheat landraces and cultivars.

TL;DR: It is shown that selection likely acts on distinct targets or multiple functionally equivalent alleles in different portions of the geographic range of wheat, suggesting either weak selection pressure or temporal variation in the targets of directional selection during breeding probably associated with changing agricultural practices or environmental conditions.
Journal ArticleDOI
Gene-specific markers for the wheat gene Lr34/Yr18/Pm38 which confers resistance to multiple fungal pathogens
Evans Lagudah,Simon G. Krattinger,S. A. Herrera-Foessel,Ravi P. Singh,Julio Huerta-Espino,Wolfgang Spielmeyer,Gina Brown-Guedira,Liselotte L. Selter,Beat Keller +8 more
TL;DR: In this paper, the authors used conserved sequence polymorphisms as templates to develop diagnostic molecular markers that will assist selection for durable multi-pathogen resistance in breeding programs, where five allele-specific markers (cssfr1-cssfr5) were developed based on a 3 bp deletion in exon 11 of the Lr34-gene.
Journal ArticleDOI
Markers associated with a QTL for grain yield in wheat under drought
TL;DR: Microsatellite marker wmc89 may be useful for marker assisted selection to enhance drought tolerance and was associated with all significant QTL covering a 7.7 centiMorgans region and generally explained the greatest proportion of phenotypic variation.
Journal ArticleDOI
Evaluation of Genomic Prediction Methods for Fusarium Head Blight Resistance in Wheat
TL;DR: This study indicates that cooperative FHB nursery data can be useful for GS, and prior information about correlated traits and QTL could be used to improve accuracies in some cases.
