摘    要:以现有的抗根肿病大白菜雄性不育甲型两用系CRAB742为不育源向本地主栽品种转育,采用同一轮回亲本,分别回交转育雄性不育甲型两用系和临时保持系。根据复等位基因遗传模式设计3种转育抗根肿病临时保持系的方法。结果表明:方法3得到的临时保持系抗病性及经济性状与来源同一材料的雄性不育甲型两用系最接近,均达到转育要求,可利用其配制抗根肿病的雄性不育系。

关 键 词:大白菜  根肿病  临时保持系  选育方法

Abstract:Anti-clubroot Chinese cabbage AB lines (type I)(CRAB42)were transferred to the main local cultivars as a source of male sterility,the same recurrent parents were adopted to backcrossing AB lines (type I) and temporary maintainer line respectively.Three methods to transfer anti-clubroot temporary maintainer line were designed based on Multiple Allele Hypothesis of genetic male sterility.The results showed that the resistance and economic traits of the temporary maintainer line obtained from the third method ...
Keywords:Chinese cabbage  clubroot disease  temporary maintainer line  breeding method
