ResumoGeographical diversity of Praxelis clematidea from eighteen various cities in Hainan were divided into five groups by RAPD-PCR cluster analysis.The first group included those from Chengmai,Haikou,Wenchang,Lingao,Danzhou and Changjiang.The second group consisted of those from Dongfang,Ledong,Sanya,Baoting,Wuzhishan,Qionghai,Wanning,Lingshui and Ding'an.Those from Tunchang,Baisha or Qiongzhong belonged to another group.The genetic similarity coefficient of each geography group of Praxelis clematidea was analyzed via NTsys-pc2.10 data processing.The genetic similarity coefficient ranged from 0.539 682 5 to 0.904 761 9,suggesting that rapid evolution was one of the methods for Praxelis clematidea biological invasion.
