摘要
[Objective] This study aimed to investigate the genetic relationship among waxberry （Myrica rubra Bieb. et Zucc） cultivars in Jiangsu Province. [ Method] Eighteen waxberry cultivars （lines） in Jiangsu Province were analyzed using ISSR-PCR method, and molecular phylogenetic tree was constructed using UPGNA method. [ Result ~ A total of 70 DNA fragments were amplified with nine screened primers, including 43 polymorphic fragments, accounting for 61.4% of the total number of amplified fragments; 18 waxberry cultivars （lines） were clustered into 6 categories with the genetic distance of 0. 14, indicating that there is partial isolation on the basis of gene exchange between waxberry cultivars （lines） in Jiangsu Province. [ Conclusion] This study provided scientific basis for the protection and utilization of waxberry germplasm resources and cultivation of new varieties.
