Abstract: In this study, 20 materials of subgenus Yulania (include species and cultivars)were analyzed using random amplified polymorphic DNA markers. 15 primers were screened from 55 arbitrary 10-mer primers, and a total of 274 DNA bands were amplified,262 of which (95.6%)were polymorphism.According to the data, a tree diagram of phylogenetic relationship was constructed using UPGMA in MEGA.The results showed that the gene background of sub genus Yulania is very complex and it was difficult to be classified. So know that the resource of subgenus Yulania in China were abundant.

Key words: Yulania , RAPD, Phylogenetic relationship
