青麻叶结球白菜雄性不育系的转育

Breeding of Nuclear Male Sterile Line in Qingmaye Type of Chinese cabbage

利用核型雄性不育系 3A作为不育源 ,以青麻叶材料黑 2 2 7为目标亲本 ,经过杂交、自交、兄妹交、测交等转育手段 ,将雄性不育基因转育到青麻叶结球白菜上 ,获得了青麻叶类型雄性不育系S10 ,其不育株率和不育度均为 10 0 % ,蜜腺正常 ,结籽正常 ,农艺性状与青麻叶类型结球白菜基本相同。对育成的雄性不育系S10进行了配合力测定 。

The male sterile line 3A was being used as a source of male sterility,the fertile line Qingmaye Hei227 as goal parent,the gene of male sterility was transferred to the Qingmaye type of Chinese cabbage by crossing,self,sibling and test crossing.The male sterile line of Qingmaye type S10 was obtained,its sterility percent and degree were all 100%,its nectary and seed were all normal.Its horticultural characters were same as Qingmaye type.The combining ability of S10 and its combinations was tested.The transferring method of genetic male sterile line was discussed.
