Abstract：Fusarium wilt is the primary factorcausing continuous croppingobstacles in watermelon，and grafting is aneffective methodforcontrollingthis disease.Linglongwang asusedasscion，and diferent materialsincluding watermeloninbred lineMo8，wild watermelon germplasm ZTC，hybrid combination M08×ZTC ，and white-seeded pumpkin were usedasrootstocks，withseedlingandself-rootedseedlingLinglongwangasthecontrol，thisstudyinvestigatedtheeffectsfourdiferent rootstock grafting treatmentson watermelongrowth，Fusarium wiltresistance，fruit yield，andqualityin protected continuous croppng fields.The results showed that compared withseedlings grown from seeds，the incidencerateand disease index Fusarium wilt in watermelonplants grafted onto the four rootstocks wereallreduced. Among them，white-seeded pumpkin exhibited the best Fusarium wilt resistance，folowed by ZTC.Grafting onto white-seeded pumpkin， ZTC，or M08×ZTC all promoted watermelon growth，with yields significantly increasing by 167.71% 67.70% ，and 51.55% ，respectively， compared to the seed-grown seedlings the Linglongwang cultivar. A comprehensive evaluation watermelon fruit quality using the subordinate function value method indicated that ZTCas rotstock improvedfruitqualitywhilegraftingontootherrootstocksledtoadeclineinquality.Therefore，ZTCcanbeused as rootstock for high-quality watermelon production in continuous cropping fields.
