Abstract：To screensuitable pumpkinrootstocks for medium-size grafted watermelon inautumn，nine hybrid pumpkin rootstocks and twocommercialrootstocks（Fengle Jinjiaand Jingxin Zhen No.4）were evaluated using Meidu watermelonas the scion.Two commercial pumpkin rootstocks（H10and H11）and self-rooted seedlings（H12）wereused as control.This study investigated theeffectsofdierentpumpkinrootstockson grafting compatibilityseedling growth，field adaptability，yield，andfruitqualityofwatermelonTheresultsindicatedthatalltestedrootstocksexhibitedhighcopatibility with watermelon.
