| 摘 要： | 通过对30份西双版纳黄瓜种质资源5个质量性状和13个数量性状的形态鉴定。结果显示:30份西双版纳黄瓜种质在形态水平上具有一定的遗传多样性。与性型分化和侧枝发生相关的5个数量性状的差异较大,变异系数较高。子叶长等8个性状差异不明显。基于形态性状的聚类分析结果,29份种质可分为5组,分组结果与其重要农艺性状基本吻合。

| Abstract: | Morphological characterization and evaluation were conducted to assess the genetic diversity in 30 Cucumis sativus L.var.xishuangbannanesis germplasm.Identification of 5 qualitative and 13 quantitative characters suggest that there was relatively abundant genetic diversity in Xishuangbanna cucumber at morphological level.5 quantitative characters related with sex differentiation and lateral branch development showed great difference.Based on above data,the result of cluster analysis expressed that 29 germpl... |
