摘要

Wild cmmer wheat, Triticum dicoccoides, is the progenitor of modern tetraploid and hexaploid cultivated wheats. Our objective was to map domestication-related quantitative trait loci (QTL) and reveal their genomic distribution in T. dicoccoides. The studied traits include brittle rachis, heading date, plant height, grain size, yield, and yield components. A mapping population F2/F3 was derived from a cross between T. dicoccoides and T. durum. Approximately 70 domestication QTL effects were detected,non-randomly distributed among and along chromosomes. Based on the significant overlapping of map locations of QTLs underlying different domestication traits, seven domestication syndrome factors (DSF) were proposed, each affecting 5-11 traits. The DSPsare probably single plciotropic genes or clusters of tightly linked genes that played a major role in the domestication process of T. dicoccoides. The genetic differentiation between cultivated wheat and its wild progenitor, displayed the following patte
