Abstract

Objective To study the genetic diversity of Liriope muscari.Methods The genetic diversity of 47 populations was analyzed by SRAP marker technique.Results Fifteen primers amplified 323 polymorphic bands,and the average percentage of polymorphic bands reached to 88.47%.The average of polymorphism information content(PIC) was 0.90.Nei’s gene diversity index(H) was 0.197 7 and Shannon’s information index(I) was 0.319 0.Gene differentiation index(Gst) was 0.252 8.Cluster analysis using UPGMA method showed that genetic similarity coefficient ranged in 0.59—0.99.Conclusion L.muscari shows higher genetic diversity and the majority of genetic variation occurs in populations.
