Abstract：To select appropriate rootstocks for grafted watermelon cultivation in Guangxi,the watermelon variety Jingmei 3K was used as the scion,with self-rooted seedlings as the control. The study investigated the effects of six pumpkin rootstocks(S1-S6)and two bottle gourd rootstocks(S7-S8)on seedling quality,field growth,fruit yield and quality after grafting with watermelon. The results showed that all the tested rootstocks exhibited good grafting compatibility and symbiotic affinity. Except for rootstock S8,the yield of watermelon grafted on all rootsocks was better than that of self rooted control,with rootstock S1 showing the most significant yield increase. In terms of fruit appearance,except for rootstocks S5 and S6,grafting with other rootstocks did not significantly alter the fruit shape of watermelon. Regarding fruit quality,rootstocks S1 and S7 performed the best. Principal component analysis and membership function analysis indicated that pumplin rootstock S1 ranked the highest. In conclusion,pumpkin rootstock S1 demonstrated good grafting compatibility with watermelon,strong resistance in the field,the highest yield,and superior quality,outperforming other pumpkin and bottle gourd rootstocks. Therefore,S1 is suitable as a pumpkin rootstock for grafted watermelon in Guangxi.
