Abstract: Choosing Podocarpus imocarpus imbricatus,Podocarpus nagi,Podocarpus fleuryi,Podocarpus neriifolius and Podocarpus macrophyllus are analysed through the RAPD techniques.Eighty primers from 4 operon kits were screened and 9 of them were able to produce clear polymorphic patterns.The results generated by using UPGMA algorithm to cluster genetic distances calulated from RAPD data imply: 1)the studied species are apparently clustered into three subgroups,which aupports the treatment of constructing corresponding sections,Sect.Dacrycarpus ,Sect.Nageia and Sect. Podocarpus in the genus Podocarpus,2)it is unreasonable to separate nageiaoids from Podocarpus and to establish a new family named Nageiaceae

Key words: Nageiaoids, RAPD analysese
