摘要: 用19 对InDel 标记对来自国内外的46 份茄子种质资源进行遗传多样性分析。结果表明:19 对InDel 标记的多态性
信息含量(PIC)范围在0.48~0.66 之间,均值为0.59。46 份茄子种质资源的遗传相似系数在0.32~1.00 之间,均值为0.70,
说明46 份茄子种质资源之间的遗传差异不大,遗传基础相对狭窄。利用UPGMA法进行聚类分析,在遗传相似系数为0.66 处,
将46份茄子种质资源划分为4大类群。聚类的结果与叶色、花冠色和果实性状具有一定的关联性,而与来源地的关联性并不大。

Abstract: In this experiment,19 pairs of InDel markers were used to study the genetic diversity of 46
germplasm resources of eggplant from home and abroad.The results showed that the PIC values of 19 pairs
of InDel markers ranged from 0.48-0.66,with 0.59 mean value.The genetic similarity coefficient of 46
eggplant germplasm resources was between 0.32-1.00 with 0.70 mean value,indicating little genetic difference
between 46 eggplant germplasm resources and with relatively narrow genetic basis.UPGMA method was
used for clustering analysis,and 46 germplasm resources of eggplant were divided into 4 groups at the genetic
similarity coefficient of 0.66.The clustering result had certain relevance with leaf color,corolla color and fruit
characters,while had little relevance with area of source.
