Genetic diversity of Perilla frutescens from Yunnan based on ISSR

Genetic diversity of 16 samples of Perilla frutescens(L.) Britt.from Yunnan Province was assessed by using 14 ISSR primers.Out of 128 amplified bands,81 of them were polymorphic and the polymorphic rate reached 62.54%.This result showed that the genetic diversity of P.frutescens in Yunnan was high.The similarity coefficients of Rogers-Tanimoto between every two samples calculated by SPSS 16.0 software varied from 0.463 to 0.882.The dendrogram of 16 Perilla samples based on ISSR data by UPGMA contained five clades corresponding to five varieties under P.frutescens.The ISSR analysis result provided molecular support for classification under Perilla resources in Yunnan.
