title: [Genetic diversity of Eucommia ulmoides by RAPD analysis].
abstract: OBJECTIVE
  To determine the genetic diversity of Eucommia ulmoides.
  
  
  METHODS
  260 samples of 20 populations were analyzed through radom amplified polymorphic DHA (RAPD).
  
  
  RESULTS
  Total polymorphic loci percentage was 96.36 and the average was 38.92. 110 bands were produced with 10 random primers and 106 were polymorphic. Nei's gene diversity (H) was 0.246 1, Shannon's Information index(I) was 0.386 8, Gst was 0.424 4, indicating that 42.44% of the genetic variation was distributed among populations and 57.65% within populations.
  
  
  CONCLUSIONS
  The genetic variation was relatively high in E. ulmoides, so the genetic diversity conservation principle should mainly focus on protection of the populations.
