| Abstract:
In this study, a total of 327 individuals of Pyrus pashia were sampled from 22 populations, mainly from Yunnan Province of China. The genetic diversity and population structure of P. pashia were analyzed using 13 nSSR markers. Pyrus pashia recorded a relatively high level of genetic diversity (He=0.721). Analysis of molecular variance (AMOVA) indicated that the genetic variation of P. pashia existed mainly within populations, representing 91.24% of the total variation. Four gene pools prevalent in different geographic populations of P. pashia were identified based on STRUCTURE analysis. Populations YN 8 and YN 10 of P. pashia with the highest genetic diversity should be given the priority when conservation strategies are implemented | |
