RAPD molecular labeling technique is used, which is analyzed the mtDNA polymorphism of the wheat sterile line and maintainer line of S-type, K-type, Ven-type and T-type by primer S22 screen out steady molecular labeling of the mtDNA with these CMS.

• 采用RAPD分子标记技术,利用引物S22 对S 型、K 型、Ven型及T 型不育系及保持系mtDNA 进行了多态性分析,筛选出稳定的并与几种细胞质雄性不育相关mtDNA的分子标记。
