1979年日本人志贺敏夫用甘蓝型油菜雄性不育遗传规律,通过品种间的杂交,按后代育性分离情况,将日本甘蓝型油菜划分为S型细胞质群和N型细胞质群两大类。我国于60年代中期开始大面积引进种植甘蓝型油菜,在生产上取得了很大的经济效益。70年代后期,尤其是80年代,又大量引进许多国外的低芥酸和低芥酸、低硫代葡萄糖甙的油菜品种,通过杂交也选育成许多新的生产用杂交种,这许许多多的油菜品种,其细胞质各属哪类,国内研究甚少。尤其是近些年来对于开展杂交油菜育种的
In 1979, Japanese Shiga Min-ku used the genetic rule of male sterility in Brassica napus and divided the Japanese rapeseed into S-type cytoplasm and N-type cytoplasm according to the segregation of later generations. China in the mid-60s began to introduce large-scale cultivation of Brassica napus in the production has made great economic benefits. In the late 1970s, especially in the 1980s, a large number of foreign rapeseed varieties with low erucic acid and low erucic acid and low glucosinolate were also introduced into many new hybrids for production through breeding. Rape varieties, which are the types of cytoplasm, little domestic research. Especially in recent years for the development of hybrid rapeseed breeding
