摘要
利用AFLP技术对包括 80份山东黄瓜地方品种和 2 4份其他地区品种的遗传亲缘关系进行了研究。用 11对引物进行选择性扩增 ,2 1%的扩增条带表现多态性。聚类分析结果显示 :山东黄瓜地方品种与日本品种和欧美品种分属不同类群或亚类群 ,山东地方品种分为 8组 ,各组内生态类型基本一致。
AFLP analysis was applied to study the genetic relationship among 80 local cucumber(Cucumis sativus L.)cultivars from Shandong province and 24 cultivars collected from other regions.11 pair of primers were screened from 128 pair of primers and generated 559 bands,21% of which were polymorphic.Cluster analysis showed that the accessions cultivated in Shandong,Japan,Europe and America were divided into different groups or sub-groups.While local cultivars of Shandong province were divided into 8 sub-groups.In addition,specific markers of four ecotypes and the genetic distance between them were also obtained.
