Abstract:: 9 types of melon were used as test materials (‘Haizhen No.1’，‘Changzhen Lishi’，‘Xianzhenda Baizi’，‘Xuezhongjia’，‘Tiemuzhen’，‘Gangjian No.1’，‘Putong Xiaozi’，and ‘New No.1’ seedling，there number were A1，A2，A3，A4，A5，A6，A7，A8（CK1） and A9（CK2）)，growth and development about graft or seedling，disease，fruit quality，yield，and so on were investigated，to select suitable watermelon rootstock.The results showed that，graft significantly increased leaf area and yield (P<0.05).At the same time，graft would length main vain，increase melon peel thickness and hardness，and improve fruit shape and flavour.But，graft would delay bloom and harvest gently.Except of ‘Tiemuzhen’(A5)，most watermelon rootstocks would decrease the incidence of blight or Pseudomonas lachrymans.Among 9 types of melon rootstocks，‘Haizhen No.1’(A1) was the most suitable one for high yield and quality and advanced disease resistance.To some degree，‘Gangjian No.1’(A6) was suitable to graft in Hainan too，with its high yield and high disease resistance.
