<![CDATA[Ralstonia solanacearum (Smith) is one of soil borne pathogens causes bacterial wilt diseases and R. solanacearum is difficult to control because it has a long survival in the soil and have many hosts alternatives. One alternative to control R. solanacearum and to increase productivity is by using grating with combination of resistant varieties of tomato as a rootstock and high production varieties of tomato as a scion. Several studies on grafting to suppress R. solanacearum were reported. However, study on grafting with combination between resistant tomato varieties (Amelia H7996) and high-production tomato varieties with R. solanacearum infestation and without R. solanacearum infestation on the component of yield and fruit quality is limited. The study aims to analyze the effect of grafting with R. solanacearum infestation to the intensity of bacterial wilt disease, component of yield, and fruit quality with R. solanacearum infestation and without R. solanacearum infestation. The result indicated that the intensity of bacterial wilt disease on grafted tomato did not significantly different from resistant rootstock but significantly different from scion. Infestation of R. solanacearum on grafted tomato can decreased the plant productivity that decreased the component of yield on grafted tomato. R. solanacearum infestation also decreased the fruit quality on diameters and fruit firmness. Nevertheless, R. solanacearum did not affect the Total soluble solid/TSS (°Brix). TSS on grafted tomato indicated that the value is taller than rootstock in the field with R. solanacearum infestation and in the field without R. solanacearum infestation.
