Study on Genetic Differentiation for Geographic Population of Davidia involucrate by RAPD Marker
- Received Date: 2004-04-13
Abstract: Davidia involucrate genetic diversity of 5 populations in distribution regions was analyzed by RAPD marker.It was found that D.involucrate possessed rich genetic diversity,however,the genetic differentiation was enormous among the populations,26% genetic variation existed among the populations due to small population effect and shortage of effective gene flow. By the use of UPGMA cluster analysis with Nei's genetic distance,D.involucrate could be soundly divided into two provenance plots of southeast and northwest,which would provide theory references for conservation and study on the development and application of germ plasm resource from D.involucrate.
