摘　　要：以普通小麦新601×雌性不育小麦XND126的F2群体作为育性调查以及基因标记群体.通过对育性基因的分析,确定在此组合中雌性不育基因由1对主效基因控制;结合混合分组分析法(Bulk Segregant Analysis,BSA),首次对小麦雌性不育基因进行了SSR分子标记,通过对一千对微卫星引物的筛选,确定微卫星引物cfd36标记与主效基因连锁,遗传距离为20.2cM.A study was carried out through the genetic analysis of F2 population which is derived from a common wheat （XIN601）and the female sterile line （XND126）, the result indicated that the sterile was condition by a pair recessive gene in the cross. The F2 population was used to mark the female sterile gene by rnicrosatellite and BSA （bulked segregant analysis） at the first time. Among the 1,000 pairs of microsatellite primers, a marker was found polymorphic between the two pools and the two parents. Linkage analysis showed that microsatellite marker cfd36 was linked with the sterile gene, and the genetic distance between the SSR marker cfd36 and the sterile gene was 22.0cM.
