摘　　要：试验对油桐[Vernicia fordii(Hemsl.)Airy-Shaw]选优数据进行了连续三年的典型相关分析,结果显示,与油桐优树综合产油因子关系较密切的生长因子首先是绝干子含仁率、鲜子出干子率、树龄、枝下高、丛生果个数,其次是干仁含水率、单果重、鲜果出鲜子率、树高、层间距。利用典型相关方程对40株决选优树进行了聚类分析,结果显示,Ⅰ类中选含油率高的单株与在Ⅱ类中选产量高的单株,可作为下一步的无性系选育目标。The canonical correlation analysis of the three-years Vernicia fordii（Hemsl.） Airy-Shaw optimal selection showed that,first growth factors integrated with the oil producing factors of V.fordii were absolutely dry seed rate with Jen,outlet dry seeds rate of fresh seeds,age of the tree,first branch height and the number of clustered fruits;and the minor factors were moisture content of the dry nut,fruit weight,fresh seeds rate of fresh fruit,height of the tree and the spacing of layers.The cluster analysis of 40 plants of V.fordii using canonical correlation equation showed that,high oil yield trees in typeⅠ and high fruit yield trees in typeⅡ could be selected as the next selection goals of ramets.
