【摘要】 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。更多还原

【Abstract】 The test of328 materials 429 times showed that a sterile line can be bred from“Shengli”(B. na-pus)or from its relative materials,a restorer line from “Yuejin”(B. napus)or “Shengli”with relation-ship of B.chinensis when new three-line are developed with Qing-2 CMS and Polima CMS system used broadly.Because of cross pollination habit of rapesead,correponding sterile and restorer line can be bred from most varieties or strain under natural reproduction for a long time. The key approach of which is direction of selection.更多还原
