Study on Genetic Diversity of Daemonorops margaritae Using RAPD

  • Received Date: 2004-08-03
  • The paper analyzed the genetic diversity of Daemonorops margaritae(Hance) Beccari using RAPD,based on four natural populations.A total of 154 sites were detected by 15 primers,which the proportion of polymorphic loci was 75.97%.The Nei's index and Shannon information index were 0.258 4 and 0.388 8,and total genetic diversity was(0.257 8).Genetic diversity of D.margaritae mainly distributed within population,which the coefficient of gene differentiation was 0.141 2.Genetic identity between Maoganxiang and Jianfengling population was the highest while that between Diaoluoshan and Bawangling population was the lowest.The results of AMOVA indicated that most of the variation(97.38%) resided within population.It was concluded from present study that there existed high genetic diversity of D.margaritae genetic resources,especially in Jianfengling population,which should be the priority population to be protected.

Abstract: The paper analyzed the genetic diversity of Daemonorops margaritae(Hance) Beccari using RAPD,based on four natural populations.A total of 154 sites were detected by 15 primers,which the proportion of polymorphic loci was 75.97%.The Nei's index and Shannon information index were 0.258 4 and 0.388 8,and total genetic diversity was(0.257 8).Genetic diversity of D.margaritae mainly distributed within population,which the coefficient of gene differentiation was 0.141 2.Genetic identity between Maoganxiang and Jianfengling population was the highest while that between Diaoluoshan and Bawangling population was the lowest.The results of AMOVA indicated that most of the variation(97.38%) resided within population.It was concluded from present study that there existed high genetic diversity of D.margaritae genetic resources,especially in Jianfengling population,which should be the priority population to be protected.
