花心大白菜核基因雄性不育系的创制

Studies on Breeding of Genetic Male Sterile Line in Chinese cabbage(Brassica rapa ssp. Pekinensis)

以白菜核基因雄性不育系(Msms)为不育源,以花心大白菜宫古花蕊Y02(MsfMsf)为轮回亲本,采用连续回交,杂交和自交的转育方法,成功地将不育基因转入到可育品系Y02中,育成了不育度和不育株率均为100%,植物学性状与Y02相近的新核不育系GMS4。

A muhiple allele inherited genetic male sterile line of Chinese cabbage was used as the source of male sterility, backcrossing, crossing and selfing were applied to transfer the male sterility to male fertile line Y02. The new inale sterile line GMS4, which contained similar botanical characters with Y02 and the sterility frequency and sterility degree were all 100%, was obtained successfully.
