Genetic Diversity and the Genetic Relationship Among Wild Types of Prunus divaricata By Using ISSR Molecular Markers
摘要
Abstract
This paper used ISSR Molecular Markers to study the genetic diversity and the genetic rela-tionship among 40 types of Prunus divaricata which originated in Tianshan Mountain of China.The study of genetic diversity and the analysis of UPGMA cluster showed that the 40 types of P.divaricate have ge-netic diversity,the average diversity index (I)was 0.488,the genetic similarity coefficient (Hs)ranged from 0.504 to 0.85 1 with an average of 0.678,the genetic distance (GD)varied between 0.127 0 and 0.604 2,the number of alleles (Na)and effective alleles (Ne)was 1.908 and 1.571 respectively,and the population has a low genetic diversity because of the average Nei's gene diversity index and the aver-age Shannon's information index (I)was 0.17 and 0.22;The 40 types of P.divaricate can be classified into 4 groups from the clustering results of molecular markers,combined with morphological analysis.The results showed that the 40 types of P.divaricate can be divided into four varieties,which were included P.divaricata var.humila (N.R.Cui et L.Wang) D.F.Cui,comb.nov.,P.divaricata var.ni-grooarp (N.R.Cui et L.Wang)D.F.Cui,comb.nov.,P.divaricata var.phoenicea (Z.Xu)D. F.Cui,comb.nov.and P.divaricata var.luteola (N.R.Cui)D.F.Cui,comb.nov..关键词
