The japanese cucumber hybrid grafting on pumpkin plants has the main objective of obtaining tolerance for soil diseases, higher yield and less wax on fruits. The behavior of the Rensei hybrid grafted on different supports was studied evaluating fruit characteristics, vegetative development of seedlings and yield as compared to non-grafted plants. The experiment was carried out in a high tunnel greenhouse, with the plants growing in plastic containers, between July/96 and July/97, in Piracicaba, SP, Brazil. The treatments used were: T1, control (non-grafted plant); T2, grafted on ‘Menina Brasileira’ pumpkin; T3, grafted on ‘Ikki’ hybrid pumpkin; T4, grafted on ‘Novita’ hybrid squash; T5, grafted on ‘Tetsukabuto’ hybrid pumpkin; T6, grafted on ‘Kirameki’ hybrid pumpkin. The graft catch was satisfactory, except to ‘Menina Brasileira’. Brighter fruits and with less wax were obtained for ‘Kirameki’ and ‘Ikki’. These two supports plus ‘Tetsukabuto’ presented a higher yield in terms of weight and number of fruits per plant.
