| 摘 要： | 应用RAPD分子标记对采自福州、三明的2个香蕉野生居群共37个个体进行遗传多样性分析.结果表明:两居群的遗传多样性水平差异不大,三明和福州两居群多态位点百分率分别为71.97%和83.12%;Ne i′s基因多样性指数分别为0.4110和0.2399;Shannon信息多样性指数分别为0.5995和0.4003.两地野生居群的遗传多样性水平较高,居群间产生的遗传分化小,居群内的遗传分化较大.在UPGMA聚类图中,除个别样本外,2个居群的个体按居群各自聚在一起,与两地野生蕉原生境考察结果一致. |

| Abstract: | The randomly amplified polymorphic DNA(RAPD) technology was applied to assess the genetic diversity and structure of 2 populations of the wild banana in Fuzhou and Sanming,Fujian Province.The percentages of polymorphic loci(PPB) of 2 populations of the wild banana in Fuzhou and Sanming were 71.97% and 83.12%,while the Shannon information indexes(I) were 0.5995 and 0.4003,and the Nei′s gene diversities(He) were 0.4110 and 0.2399,respectively.The genetic diversities of the 2 populations of wild banana were at relatively high level,and the genetic differentiation mainly occurred within the population.The UPGMA cluster analysis showed that the 37 individuals of the wild banana were clustered into 7 clusters corresponding to the 2 populations except for a few individuals. |
