柳枝稷种质遗传多样性的SSR分析
Genetic diversity of switchgrass(Panicum virgatum) germplasm detected by SSR markers
摘要
Abstract
In this experiment,seven SSR marker primer pairs were used to detect the genetic diversity of 10 accessions of switchgrass(Panicum virgatum).The results showed that the polymorphism information content(PIC) of different materials were ranged from 0.669 to 0.881,and the genetic similarity coefficient ranged from 0.385 4 to 0.905 7.UPGMA(Unweighted Pair Group Method with Arithmetic Mean) was used for clustering analysis of the 10 accessions,based on the genetic distance and polymorphism information detected by the SSR markers.Five breeding varieties and the wild germplasm No.2 exhibited a closer genetic relationship and were clustered into one group,whereas the rest five accessions were clustered into the other group.The clustering result of the primer pair 5211_B07 was the same as that of the genetic distance.关键词
