大白菜细胞核雄性不育基因向卵圆型大白菜‘160’的转育

Introgression of genic male sterile gene of Chinese cabbage into ovate ecotype Chinese cabbage variety

根据大白菜复等位基因遗传假说,运用合成转育模式将大白菜‘189’细胞核雄性不育基因转入基因型为msms的卵圆型白菜‘160’中,获得了卵圆型白菜‘160’的新甲型"两用系"及相应的不育系和保持系。

Based on the Multiple Allele Hypothesis of genic male sterility,the synthesis transferring method was used to transfer the gene of male sterility into the orbicular-ovate type Chinese cabbage variety 160 ,whose genotypes were msms by crossing,inbreeding,sibling and test crossing.New AB lines type I,new male sterile lines and their corresponding temporary maintainer lines of Chinese cabbage variety 160 were obtained from the transferred progenies of the Chinese cabbage variety 189 .
