摘　　要：以复等位基因遗传的白菜核基因雄性不育系06sx110为试材,设计定向转育方案,采用连续回交转育性状的同时,测交筛选基因型的方法,向小菘菜自交系Y05中转育雄性不育基因,育成了不育株率和不育度均为100%、园艺学性状与自交系Y05相近的小菘菜核基因雄性不育系GMS3。A directional transfer program was designed by using multiple allele inherited genetic male sterile line 06sx110 as the source of male sterility,and recurrent backcrossing was employed to transfer botanical traits,while the genotype was identified through test cross.Following this procedure,the male sterile gene was transferred to the target parent Y05 successfully.A new male sterile line GMS3,which is similar to Y05 on botanical traits with 100% male sterility and 100% male sterile plants,was bred.
