title: [Studies on genetic diversity of medicinal Dendrobium by SRAP].
abstract: OBJECTIVE
  To study the genetic diversity of medicinal Dendrobium by SRAP.
  
  
  METHODS
  The genetic diversity of 9 spices Dendrobium was studied by using the optimized SRAP reaction system. The NTSYS software was used to analyze the markers.
  
  
  RESULTS
  Forty primer pairs were selected from 88 amplified 1 782 polymorphic bands with an average of 44.55 polymorphic bands per primer pair. Cluster analysis using UPGMA method based on the data of SRAP amplified bands by 40 primer pairs showed that 9 spices of could be distinguished into two main groups. Jaccard's similarity coefficient ranged from 0.330 2-0.789 2.
  
  
  CONCLUSIONS
  The results of this research indicate that SRAP molecular marker is efficient to study the medical Dendrobium genetic diversity.
