摘要
海沃德为世界著名美味猕猴桃品种，以它为母本进行品种间杂交育种，其Ｆ＿１出现许多优良变异，为优株选择奠定了基础。对海沃德杂种Ｆ＿１进行了主成分分析，并计算出Ｆ＿１群体内各单株在重要主成分上的得分，进而选出综合性状优良的单株。
In this study principal component(PC)analysis was performed with phenotype data of Hayward ki-wifruit seedlings to evaluate its suitability for identifying superior kiwifruit vines in a breeding programme.PC pattern was assessed to quantify the characters most powerful in distinguishing between seedlings.seedlings were placed in order of their PC scores which represent overall merit,and the superior ones weredetermined. The results in this study showed that the best male vines for early vigour and high florifer-ousness, and the female vines with high yield and vine efficiency could be easily determined by PC analysis forHayward cross.
