摘　　要：油菜是重要的油料作物,其授粉方式对自交亲和性的影响较大。该试验通过对参试材料采用自由授粉、套袋自交两种授粉方式,并分析黄籽油菜与非黄籽油菜的自交亲和性。结果发现,黄籽油菜的平均结角率均低于非黄籽油菜。而对于每果粒数而言,除原油706056、黄油1号、贡麦黄籽外,其余黄籽油菜的套袋自交每果粒数为7.66粒、自由授粉的每果粒数为10.10粒;非黄籽油菜的套袋自交的每果粒数为2.83粒、自由授粉的每果粒数为13.88粒,参试黄籽油菜材料的自交亲和指数普遍高于非黄籽材料,且黄籽油菜与非黄籽油菜之间自交亲和指数相差为4.2。该研究对于白菜型油菜的改良和选育具有重要意义。Rape is an important oil crop,and its pollination method has a great influence on self-inbred affinity.In this study,two pollination methods,namely free pollination and bagging self-pollination,were adopted to analyze the self-inbreeding affinity between yellowseed rape and non-yellowseed rape.The results showed that the average podding rate of yellowseed rape was lower than that of non-yellowseed rape.Except for crude oil 706056,butter No.1 and Gongmai yellow-seeded rapeseed,the number of seeds per fruit of bagging and self-inbred of yellowseed rape was 7.66,and the number of seeds per fruit of free pollination was 10.10.While for the non-yellowseed rape,the number of seeds per fruit of bagging and self-inbred was 2.83,and the number of seeds per fruit of self-pollination was 13.88.The self-inbred affinity index of the tested yellowseed rape materials was generally higher than that of non-yellowseed materials,and the difference in self-inbred affinity index between yellowseed rape and non-yellowseed rape was 4.2.This study is of great significance for the improvement and breeding of Brassia campestris L.
