Title: Genetic Diversity and Population Structure Analysis by Using SSR Markers in Barley
Abstract: The genetic diversity among 99 barley parent materials from different regions and population structure were analyzed by 71 pairs of SSR primers to provide useful information for hybridization combination and association mapping in barley. A total of 184 locus were detected,ranged from 2 to 5,with 2. 6 locus in average per marker. Shannon index ranged from 0. 0565 to 1. 2241,with the mean of 0. 6086. The polymorphism information content( PIC) value ranged from 0. 0200 to 0. 6633,with the mean of 0. 3729. Clustering analysis showed that the genetic similarity coefficient( GS) ranged from 0. 5109 to 0. 9511,the mean of which was 0. 7202. At the genetic similarity coefficient level of 0. 7100,99 materials could be clustered into 5 groups,including 5,4,3,6 and 79 materials,respectively. 5 subgroups could be sorted by principal coordinate analysis,including 5,10,12,24 and 26 materials,respectively. After population structure analysis,these materials could also be divided into 5 subgroups,which included 24,18,6, 22and 29 materials.
