The oriental melon Jinguanwang was used as scion,Qiangshi,Elizabeth,Yongshi and Qiangli as rootstocks for grafting,self-rooted seedlings as controls,the growth,fruit yield,and quality of melon plants grafted on different root-stocks were investigated.Principal component analysis was used for comprehensive evaluation,in order to screen suitable rootstock varieties for the oriental melon Jinguanwang grafting.The results of the investigation and analysis of the indexes showed that the plant height,number of branches,and number of internodes of Yongshi grafted seedlings were significant-ly higher than that of the control.The single fruit weight of Qiangshi grafted seedlings was significantly increased 46.65%,and the yield per 667 m2 of grafted seedlings of Qiangshi,Elizabeth,and Yongshi is significantly increased 24.54%、10.36%、19.96%,respectively.The vitamin C content of Qiangshi,Yongshi and Qiangli grafted seedlings significantly in-creased 44.48%、82.23%、89.25%,respectively.The results of principal component analysis showed that the grafted seed-lings of Qiangshi and Yongshi rootstocks performed the best and were suitable as grafting rootstocks for Jinguanwang.
