Cultivar Classification of Dendrocalamopsis oldhami with RAPD Molecular Markers

Polymorphic analyses on 22 cultivars of Dendrocalamopsis oldhami were made by means of RAPD technique.20 effective primers with 10 bp were screened out of 94 primers, totally 113 DNA loci were amplified, and 91 of these loci were polymorphic (accounting for 80.5%).The UPGMA cluster analysis of POPGEN32 program showed the following results:The cultivars of Dendrocalamopsis oldhami could be classified by UPGMA analysis.The genetic distance among the studied cultivars was between 0.122 2 and 0.815 4, and most of the genetic distance was below 0.6.The technique of RAPD molecular markers was helpful to the under species classification of bamboo plants.
