Abstract In view of the serious harm of soil-transmission diseases of bitter gourd caused by years of continuous work，the effects of different loofah rootstock on the affinity，growth potential，disease resistance，yield and quality of spike balsam pear were studied through grafting cultivation experiments on 17 loofah rootstock varieties and bitter gourd spikes such as ‘Ruyu 178’．The results show that different loofah rootstock grafting can obviously reduce the incidence of bitter gourd wilt，and its yield is significantly better than that of self-rooted seedlings．The overall impact of different rootstock grafting on the water，protein，coarse fiber，VC，etc.，of the spike balsam pear fruit is have varying degrees．Through the analysis of the correlation between the agronomic traits of different grafted rootstock treatments and the yield of balsam pear，there is a very significant positive correlation between yield and stem coarse stem，main creep，melon length，melon transverse diameter and single melon quality．Based on the analysis results of various traits，the rootstock-17 and rootstock-15 perform well in affinity，yield，quality and disease resistance，which is suitable for demonstration and popularization as balsam pear grafting rootstock．
