摘　　要：利用生化标记辅助选择与温室加代回交育种相结合的方法,将优质高分子量谷蛋白亚基14+15与5+10的基因分别导入和聚合到高产杂交小麦西杂一号亲本,用含有目标亚基的杂交小麦亲本组配杂交组合,获得含有单个优质亚基14+15、5+10和聚合这两种优质亚基的西杂一号,在保持原品种高产性状的同时提高了其HMW-GS组成品质评分,有望实现杂交小麦高产优质.High molecular weight glutenin subunits 14＋ 15 and 5＋10 with good quality properties were introduced into the parents of high-yielding hybrid wheat XZ1 through biochemical marker assisted selection and greenhouse backcrosses breeding,and then gained hybrid wheat with 5＋10,14＋15 ,and pyramided 5＋ 10 and 14＋ 15 though cross-fertilize between parents with good HMW-GS. The results indicated that quality score of hybrid wheat was increased while maintaining the original high yield. It is hopeful to realize both high yield and good quality of hybrid wheat.
