High-density genetic linkage maps are necessary for precisely mapping quantitative trait loci (QTLs) controlling grain shape and size in wheat. By applying the Infinium iSelect 9K SNP assay, we have constructed a high-density genetic linkage map with 269 F 8 recombinant inbred lines (RILs) developed between a Chinese cornerstone wheat breeding parental line(More)
Introgressive hybridization has played a crucial role in crop breeding. Powdery mildew-resistant gene 21 (Pm21), located on the short arm of chromosome 6V of Haynaldia villosa (H. villosa), is typically a representative element which is transferred to hexaploid wheat through introgressive hybridization. Determination of sequence evidence for H. villosa DNA(More)
