[Objective] Study on the genetic diversities of A.splendens from different areas of xinjiang.[Method] The genetic diversities among seven populations and within two populations were analyzed by RAPD.[Result] Genetic clustering results presented that the relationships among populations of A.splendens are directly related with geographic positions,and within population are related with habitats.[Conclusion] RAPD technique can be used to study genetic diversity of A.splendens.
