In order to evaluate the diversity level of Xinjiang Bermudagrass,the genetic diversities of Bermudagrass from Xinjiang,Huanan and abroad were investigated using SSR marker.Results indicated that 142 allelic variations were amplified by 20 primers,of which 124 were polymorphism and each locus had 7 allelic variations.The percentage of polymorphic loci was 87.86％,the average of Nei's (H) was 0.4347.The genetic similarities (GS) of 106 materials ranged from 0.43 to 1.0,the average was 0.715.The genetic differentiation coefficient was 41.19％ among the population and 58.81％ inside the population.Data illustrated genetic variation within populations was larger than among populations according to genetic identity and differentiation.The general clustering consequences by UPGMA method indicated that 106 materials were classified into three groups when the similarity coefficient was 0.39.The genetic variance of Bermuda grass was not obviously related to the origin,but the materials from the same region were more classified into the same group.These clustering results were correlated with geographic origin in some extent.
