Abstract

Abstract: Contrasted with 2 different Loropetalum chinense ecotypes, fourteen Lorop etalum chinense var. rubrum materials representing almost all the types could be were analyzed by RAPD in this paper. Fifty􀀁five random primers produced 632 steady amplified bands in total, among them 427 bands were polymorphic. Strong and clear bands were scored for their presence or absence in a binary data matrix. Nei's similarity coeff icients and genet ic
distances were calculated by NTSYS􀀁pc software, and principal components analysis was done by SAS software. The result demonstrated that L . chinense var. rubrum is a mutant of L . chinense on molecular level and 14 L.
chinense var. rubrum materials were classified into 4 groups. The mutant pathway of 4 groups is possibly a complicated process, including interactions between different ecotypes L . chinense, interactions between L.
chinense and L . chinense var. rubrum, and ineractions between different L . chinense var. rubrum.

Key words: Loropetalum chinense var. rubrum, RAPD, Genetic distances, Cluster analysis
