The Ralstonia solanacearum is one of the main root pathogens of the tomato in North of Brazil. The control is dificult instead, there are no resistant cultivars and no efficient chemicals control. In this study, the use of wild Solanaceas, cubiu (Solanum sessiliflorum), jurubeba (Solanum viarum) and tomato cultivar Yoshimatsu as rootstockswere evaluated. The cv. Santa Cruz Kada Gigante (SCKG), susceptible to bacterial wilt, were used in the graft and rootstock combinations: SCKG/cubiu, SCKG/jurubeba, SCKG/Yoshimatsu, SCKG/autograft and SCKG ungrafted. Were quantified the incidence and symptom development, height and diameter of plants, numbers of flowers and fruits per plant. Plants grafted on cubiu did not develop symptoms of the disease. Yoshimatsu showed partial resistance and increased growth and productivity in grafted plants.
