ABSTRACT
<p><b>OBJECTIVE</b>To study the genetic diversity of medicinal Dendrobium by SRAP.</p><p><b>METHOD</b>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.</p><p><b>RESULT</b>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.</p><p><b>CONCLUSION</b>The results of this research indicate that SRAP molecular marker is efficient to study the medical Dendrobium genetic diversity.</p>
