白菜类蔬菜作物100%核基因雄性不育系(简称“不育系”)是一类较理想的雄性不育材料,日益成为人们研究的热点。转育是获得100%不育系的简便而有效方法。根据大白菜核不育系“复等位基因遗传假说[1]”,设计了可育品系雄性不育系3种转育模式并提出核不育系制种方法。
The 100% nuclear gene male sterile line (“CMS”) of the cabbage vegetable crop is a kind of ideal male sterility material, which has increasingly become the hot spot of people’s research. Regenerating is a simple and effective way to get 100% sterile lines. According to the “complex allelic genetic hypothesis [1]” of Chinese cabbage male sterile line, three breeding modes of male sterile line of fertile line were designed and the method of seed production of nuclear sterile line was proposed.
