摘　　要：安徽羽叶报春是我国特有的一种珍稀濒危花卉。论文对自花授粉在其花色选育中的应用进行了初步研究。结果表明:安徽羽叶报春自花授粉亲和性较高,平均结籽数可达36.03粒/果,能达到正配授粉结籽数的71.11%(正配授粉结籽数为50.69粒/果),而且自花授粉种子也基本能正常萌发,萌发率为41.13%,达到正配授粉种子萌发率的57.98%。花色分析显示自花授粉子代花色R值比重均值(即红色成分,为0.382)显著高于其亲本群体及正配授粉子代的均值(均为0.375左右)。因此安徽羽叶报春自花授粉虽存在一定的衰退现象,但它有利于花色的选育和纯合品系的获得,在其花色的选育过程中应加以重视和利用。Primula merrilliana is a rare ornamental flowers species and endemic to China. We preliminarily studied the application of self pollination in the selection and breeding of its flower color. The compatibility of self pollination in P. merrilliana was relatively higher, the average number of seeds was up to 36.03 per fruit, which reached 71.11% of the seeds of legitimate pollination （50.69 seed per fruit） , and the germination rate of self pollination seeds was up to 41.13% , which was 57.98% of seeds germination rate of legitimate pollination. The analysis of flower color showed that the mean value of R of self pollination progeny population （0. 382） was significantly higher than that of the parental population and the progeny population of legitimate pollination（ both was about 0. 375 ）. Therefore, we should pay attention to the application of self pollination in the breeding of P. merriUiana because it is beneficial for flower color selection and obtaining of homozygous lines, although there is a certain level of inbreeding depression.
