摘要
用105对茄子SSR引物对34份茄子高代材料进行遗传多样性分析。试验结果表明:47个标记在供试材料中有多态性,共检测出148个多态性位点。多态性信息含量(PIC)的变化范围是0.0254～0.9093,显示了较高的多态性。供试材料遗传相似系数在0.63～0.93之间,供试材料之间的遗传差异不大,遗传基础相对狭窄。利用UPGMA聚类分析,将供试材料归为两大类4个亚类,SSR分子标记与果实性状聚类分析结果基本一致。
105 eggplant(Solanum melongena L.)SSR markers were used to analyze the genetic polymorphism of 34 eggplant high generation materials.The result indicates that there are 47 markers showing polymorphisms among the tested materials which have 148 polymorphism sits.The polymorphism information content(PIC)varies from 0.025 4-0.909 3,showing high genetic polymorphism.The similarities coefficient of the tested materials was between 0.63 to 0.93,implying little genetic differences and relatively narrow genetic base.By UPGMA cluster analysis,we classified the tested materials into 2 clusters and 4 sub-clusters.The result of SSR molecular marker is almost the same with that of fruit trait cluster analysis.
