The 54 accessions were classified into five major groups:Ⅰ,Ⅱ,Ⅲ,Ⅳ and Ⅴ by cluster analysis using UPGMA, which showed significant relationship with the origin regions of accessions. Genetic differentiation between and within eight eco-geographical groups of C.dactylon was estimated by Shannon's diversity index, which showed that 63.81% genetic variance existed within group, and 36.19 % genetic variance was among groups, indicating rather large genetic distances among those germplasm, and there was a correlation between genetic differentiation and eco-geographical habits among the groups.
