摘　　要：用PCR方法在大白菜新型雄性不育系RC7中克隆出与雄性不育基因相关的片段,该片段与NCBI发布的orf138具有高度同源性,同源性为100%。说明RC7的不育机理与Ogu-CMS具有相似性,也证明了CMS基因的相对保守性。为RC7的利用奠定了理论基础,充实了大白菜细胞质雄性不育理论。The special sequence related to CMS was amplified in the new Chinese cabbage CMS RC7 by PCR amplifying, and its homology is 100% with orf138 published in NCBI. This not only indicated that RC7 has the similar sterility with Ogu-CMS, but the gene related to CMS is relative conservative. The result both established the theory for full utilization of new variety RC7 and enriched the CMS theory.
