对国内外３２８份甘蓝型油菜种质资源４２９次测定，结果表明，利用Ｑｉｎｇ－２Ａ及ＰｏｌｉｍａＡ选育新的三系，可以从胜利油菜或具有胜利油菜亲缘的种质材料中育成保持系，从具有跃进油菜亲缘及具有中国南方白菜型油菜的胜利油菜种质材料中育成恢复系。然而，由于油菜异交授粉习性，多数长期自然繁殖的品种（系）都可能筛选出相应的不育系和恢复系，关键在于选择的方向。
A total of 429 germplasm resources of Brassica napus at home and abroad were determined 429 times. The results showed that the maintainers could be bred from the germplasm of Shengli rape or the rapeseed by using Qing-2A and PolimaA to breed new three lines. Regeneration of rapeseed germplasm with Lijin rape relatives and rapeseed with Chinese southern cabbage rape. However, due to rapeseed cross-pollination, most long-term natural breeding varieties (lines) may screen out the corresponding sterile and restorer lines, the key lies in the direction of selection.
