中文摘要	sequence-related amplified polymorphism (srap) markers were used to assess the genetic diversity and population genetic structure in fourteen wild populations of lycium ruthenicum from northwestern china. thirty-one selected primer combinations produced 468 discernible bands, with 398 (85.04%) being polymorphic, indicating relatively high genetic diversity at the species level. analysis of molecular variance showed that the genetic variation was found mainly within populations (84.45%), but variance among populations was only 15.55%. and there was a moderate genetic differentiation (g(st) = 0.2155) among populations. mantel test revealed a significant correlation between genetic and geographic distances (r = 0.303, p = 0.004), and the unweighted pair-group method using arithmetic average clustering and principal coordinates analysis demonstrated similar results. a total of nine significant (p < 0.05) correlations were detected between three indices of genetic diversity and seven ecogeographic factors. also recommendations for conservation of the endangered species resources and breeding program are proposed.
