| 摘 要： | 对不同来源的85份白菜型油菜品种的自交亲和指数研究表明,白菜型油菜的自交亲和性存在较大幅度的变异,自交亲和指数在0．00～9．28之间,这种变异不仅存在于品种间,而且存在于品种内不同个体间。85份参试材料中,自交亲和指数小于1的有50个品种;35个品种自交亲和指数大于1,自交亲和指数在1．00～9．28之间,其中亲和指数大于4的材料有28、44、45、55x、75、119、123、139号品种等。依据自交亲和指数,可将参试材料分为4种类型:高自交亲和类型(自交亲和指数>4．00);自交亲和类型(自交亲和指数1．00～3．99);自交不亲和类型(0．00< 自交亲和指数<1．00);高自交不亲和类型(自交亲和指数=0．00)。自交亲和性因地区而异,一般西部地区的品种自交亲和性高于其它地区的品种。

| Abstract: | The self-compatible indexes of 85 varieties from different sources were studied, which indicated that Brassica rapa self-compatibility varied within a relative great range,the self-compatible indexes ranged within 0. 00-9. 28 and this variation existed not only among the species but among different plants of the same species. If the 85 materials under study ,50 varieties had a self-compatible index less than 1 and 35 varieties had a self-compatible index of more than 1,which ranged within 1. 00-9. 28,and the varieties with a self-compatible index of more than 4 were 28,44,45,55x, 75,119,123 and 139. According to their self-compatible indexes,the varieties under study could be divided into four types :type of high self-compatibility (self-compatible index>4.00), type of self-compatibility self-compatible index ranging within 1. 00 -3. 99),type of self-incompatibility (0. 00
