| 摘 要： | 以收集的8个绢毛蔷薇居群的80份样本为研究对象,利用SSR技术分析其遗传多样性.80个样本的多态位点百分率、Nei's基因多样性指数(H)和Shannon信息指数(I)分别为69.66％、0.1425、0.2296.比较8个居群的遗传多样性指标,显示居群间遗传变异55.53％,居群内遗传变异44.47％.茂林居群的遗传多样性最高(H=0.0879,I=0.1331,多态位点百分率为25.84％).聚类分析结果显示,8个居群可聚类为2组.居群遗传分化系数(Gst)和基因流(Nm)分别为0.5553和0.4005,表明绢毛蔷薇基因分化明显,基因交流受阻.

| Abstract: | Simple sequence repeat(SSR) analyses were conducted to assess the genetic diversity of eight Rosa sericea Lindl populations,which showed that relatively abundant genetic diversity existed in Rosa sericea Lindl populations.The percentage of polymorphic loci,Nei's gene diversity(H) and Shannon information index(I) of 80 samples were 69.66 %,0.1425 and 0.2296,respectively.The indexes of genetic diversity showed that the genetic variation within and among eight populations was 44.47 %,55.53 %,respectively.The g... |
