为了扩大恢复源,1988-1989年用49个甘蓝型、芥菜型品种与波里马不育系测交,发现三个全恢材料。波里马不育胞质F_1的生育期、菌核病的感染程度和经济性状无不良负效应。选育冬播油菜不育系比选育春播油菜不育系要困难。本文还对油菜的起源进化与三系选育的关系进行了讨论。 In order to expand the restoration source, 49 full-length Brassica juncea varieties and Polima sterile lines were detected from 1988 to 1989 and three full-length materials were found. Polima sterile cytoplasm F_1 growth period, sclerotinia infection and economic traits without adverse effects. Breeding winter seeding CMS lines is more difficult than selecting spring seeding CMS lines. The paper also discussed the relationship between the evolution of rape origin and the selection of three lines.
