Genetic Diversity Analysis of Rice PTGMS Lines Based on SSR Markers
摘要
Abstract
The genetic diversities of 17 rice PTGMS lines were analyzed by adopting 168 pairs of SSR markers which were evenly distributed on the 12 chromosomes of rice.Among these 168 pairs of SSR markers, 91 pairs of SSR markers showed a polymorphism with the polymorphic frequency of 54.17%.A total of 229 alleles were detected with these 91 polymorphic SSR markers, and the number of alleles per SSR locus ranged from 2 to 4 with an average of 2.517.The average polymorphic information content index was 0.412.According to the genetic similarity coefficient matrix of the tested 17 rice PTGMS lines, a dendrogram was constructed by UPMGA, and a clustering analysis was conducted, the results showed that the range of genetic similarity coefficient of 17 rice PTGMS lines was 0.59~0.93.When genetic similarity coefficient 0.61 was used as a threshold, the tested rice PTGMS lines could be divided into four groups, which was basically consistent with their pedigree relationship.关键词
