Abstract:
To explore the genetic diversity of Prunus salicina L.and Prunus armeniaca L.,the genetic diversity of 27 plum and apricot varieties grown in the north were analyzed by using SSR molecular marker technology,and the genetic relationship were analyzed by using UPGMA clustering analysis method in this study in order to provide molecular biological basis for the preservation and breeding of germplasm resources.The results showed that,245 alleles were amplified by 25 pairs of SSR primers and including 240 polymorphic loci,the ratio of polymorphism was 97.96%,4-13 alleles were amplified by per pairs of primer,with a mean of 9.8.The average of effective alleles was 2.740 5,the average of Shannon′s information index was 1.052 0,the average of polymorphism information content was 0.595 5,illustrated the germplasms with high genetic diversity.The clustering analysis results showed that,when the genetic correlation coefficient was 0.612,the 27 resources could be divided into two big groups of plum and apricot.
