| Abstract: | 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. |
