Abstract We studied the survival rate of grafted bitter gourd（Momordica charantia L.）, and effects of grafting on plant growth and development, phytophthora blight controll, its yield and product quality by 4 rootstocks. The results showed that these 4 rootstocks grafted with‘Xiangzaoyou No.1’had no effect on the plant chlorophyll content, fruit yield and quality, but had good controlling effect on phytophthora blight. Among the 4 rootstocks,‘Weilong No.1’had the best grafting effect. Its survival ratio reached 98 % and blight morbidity was only 1.7 %, disease index was 3.4. Its yield increased 63.2 % than the self-rooted plant.
