Based on the natural distribution of Caragana korshinskii Kom.in China,ten populations of C.korshinskii of Inner Mongolia and Loess plateaus were evaluated by their phenotypic diversities.Main results obtained are as follows: morphological diversities among within populations such as those shown in the leaves,pods,and seeds exposed significant differences among populations and among individuals within populations.The mean phenotypic differentiation coefficient(V_(ST)=0.195) shows that the variation among populations(80.5%) is significantly higher than that within populations.The correlations between the phenotypic traits and ecological and geographic factors are not significant.Based on the cluster analysis,the populations of C.korshinskii investigated may be divided into four groups by phenotypic traits.A thousand-seed weight,pod width,and leaf length were the main traits account for the phenotypic variations by discriminant analysis.
