摘要

A combined approach using nuclear SSRs and cpDNA non-coding regions was taken to study the genetic diversity and population structure of Pyrus calleryana in Zhejiang province of China. Fourteen nSSR makers and two cpDNA intergenic regions were used to study 77 individuals from 8 populations. AMOVA analyses indicated that the majority of the genetic diversity occurred within populations. Mantel tests showed that the genetic distance was significantly correlated with the geographic distance (nSSRs: r=0.592, p=0.008; cpDNA haplotype: r=0.332, p=0.048). STRUCTURE analyses exhibited that there were 2 gene pools among populations. All of the populations could be divided into 2 groups which correlated with geographic regions (northeast and southwest). Geographic distance was a key factor in shaping the current genetic structure of the P. calleryana. Population FY was the most suitable population to be protected under in situ conservation strategy.
