Genome-wide association mapping for grain shape and color tr

发布时间：2021-05-17 10:46

　　Grain shape and color strongly influence yield and quality of durum wheat. Identifying QTL for these traits is essential for transferring favorable alleles based on selection strategies and breeding objectives. In the present study, 192 Ethiopian durum wheat accessions comprising167 landraces and 25 cultivars were genotyped with a high-density Illumina i Select 90 K singlenucleotide polymorphism（SNP） wheat array to conduct a genome-wide association analysis for grain width（GW）, grain length（GL）,...
