采用蕾期剥蕾授粉的方法,成功获得了新疆野生油菜野油2000-1和甘蓝型油菜Parol属间杂种.杂种F1育性极低,自由授粉条件下获得少量F2种子.在F2群体中成功选择到一株雄性不育株,用Parol做轮回亲本与不育株回交,BC_1、BC_2和BC_3群体中可育株与不育株均呈1:1分离.用波里马细胞质雄性不育的保持系和恢复系、681A的保持系和恢复系、隐性核不育86A的保持系及其它33个甘蓝型油菜品系与BC_2群体中的不育株测交,测交后代可育株与不育株呈5:3分离的组合有20个,呈1:1分离的组合有14个,呈3:1分离的组合有3个,有一个组合的后代完全可育,表明该雄性不育材料可能为显性核不育.

Intergeneric hybrids between Sinapis arvensis （Yeyou 2000 - 1 ）and Brassica napus var. Parol were produced by bud - pollination. The hybrids were amost sterile and only a few F2 seeds were harvested under the natural condition. A male sterile plant 200210 - 1 showing no pollen release upon flowering was selected from F2 population after open pollination. Using Parol as a recurrent parent to pollinate the male sterile plant, the ratio between male fertile and sterile plants was I： I in BC1 ,BC2 and BC3 generations. All except one F1 progenies...
