小白菜杂交种青杂油白菜1号选育研究

Study on Hybrid Qingzayoubaicai No.1 Breeding of a Variety of Chinese Cabbage

将白菜型油菜Polima不育胞质导入小白菜中转育出育性稳定的小白菜不育系PolimaCMS 02979A,用该不育系与选育的自交系7S两系配套选育出青杂油白菜1号新品种,该品种高产、优质、生长速度快、抽薹晚且耐寒抗病,于2006年通过青海省农作物品种审定委员会审定。

By transferring Polima cytoplasm sterile genes from B. campestris L. into a variety of Chinese cabbage, new type PolimaCMS line such as a variety of Chinese cabbage 02979A was bred, which crossed with self-crossing line 7S and bred out new variety Qingzayoubaicai No. 1, the variety authorized by QACC in 2006 had characters such as high production, high quality, quick growing, delayed bud appearance, cold tolerance and disease resistance.
