Genome-wide association study in historical and contemporary

发布时间：2021-06-27 14:21

　　Plant height has been a major target for selection of high-yielding varieties in wheat. Two height-reducing loci（Rht-B1 and Rht-D1） have been widely used since the Green Revolution.However, these genes also negatively affect other agronomic traits such as kernel weight.Identifying alternative height-reducing loci could benefit wheat improvement. This study focused on the genetics of plant height in 260 historical and contemporary winter wheat accessions via genome-wide association studies using ...
