选用38对SSR引物,对16个日本优质米品种越光及其近缘品种进行了 SSR标记分析。结果表明,有 8 对引物在品种间表现多态性,多态性引物检出率为21.1%,平均每对引物检测到2.25个等位基因。8个引物组合在一起,除了早喜光和日光2个品种不能区分外,其余品种均能有区别。多态性检出率亲本间为 18. 4%,越光及其衍生品种间为 0 ~15 8%,表明近缘品种间多态性检出率较低。 Thirty-eight pairs of SSR primers were used to analyze the SSR markers of 16 high-quality japonica rice cultivars and their related cultivars. The results showed that 8 pairs of primers showed polymorphism among cultivars. The detection rate of polymorphic primers was 21.1%, and the average number of alleles per primer pair was 2.25. Eight primers together, except for early hi light and sunlight can not distinguish between the two varieties, the rest of the species can have a difference. The detection rate of polymorphism was 18.4% among parents, and between 0-158% in Koshihikari and its derivatives, indicating that the detection rate of polymorphism among the related varieties was low.
