Abstract：To screen suitable pumpkin rootstocks for medium-size grafted watermelon in autumn,nine hybrid pumpkin rootstocks and two commercial rootstocks(Fengle Jinjia and Jingxin Zhen No.4)were evaluated using Meidu watermel-on as the scion.Two commercial pumpkin rootstocks(H10 and H11)and self-rooted seedlings(H12)were used as con-trol.This study investigated the effects of different pumpkin rootstocks on grafting compatibility,seedling growth,field adaptability,yield,and fruit quality of watermelon.The results indicated that all tested rootstocks exhibited high compati-bility with watermelon.Grafted seedlings demonstrated superior quality,growth vigor and yield compared to self-rooted seedlings.H1,H2,H7,H8,and H9 showed better yield;H2,H6,H7,H8,and H9 exhibited superior intrinsic fruit quality compared to the commercial rootstocks.Through principal component and membership function analysis of 21 key indica-tors,rootstocks H9,H7,and H8 were comprehensively evaluated as superior to Fengle Jinjia and Jingxin Zhen No.4 in terms of seedling strength index,yield,soluble solids content and sensory evaluation score,increasing yield by 20.45％-27.98％compared to self-rooted plants.These pumpkin rootstocks are recommended as suitable options for medi-um-size grafted watermelon cultivation in autumn,particularly in ecological zones with conditions similar to those of Hu-bei province.
