| 摘 要： | 为了明确我国茄子主要栽培种的遗传背景,对主要来自广西及全国部分地区的54份茄子栽培种进行表形标记和ISSR标记分析.结果表明,在37个表形性状中,表现为多态性有33个,占89.18％；从50条ISSR引物中共筛选出8条多态性明显、条带清晰、反应稳定的引物,扩增出68条谱带,平均每条引物扩增出8.5条带,多态性带58条,占85.29％；品种间两类型标记遗传相似系数均在0.04 ～1.00之间,总体平均数分别为0.51、0.60,表明个别品种间遗传差异很大,但群体整体遗传基础相对较狭窄；应用SPSS软件聚类分析,两类标记均能在欧氏距离14～15间将54个栽培种划分为6个类群,其中表形标记类群的划分与地理来源有一定关系,而分子标记类群的划分与地理来源没有明显的联系.

| Abstract: | To make clear the genetic background of the dominant eggplant germplasm species in China,54 eggplant cultivars from Guangxi and other parts of China were assessed with Morphological markers and ISSR markers.The results indicated that: 37 phenotypics were observed and 33 phenotypics(89.18 %) were polymorphic;8 polymorphic primers were selected from 50 ISSR primers.68 DNA fragments were amplified and each primer resulted in 8.5 DNA fragments on average.58 fragments were polymorphic(percentage of polymorphic b... |
