Summary Galia‐type melons grafted on to the Cucurbita rootstock‘TZ 148’and non‐grafted controls were evaluated for vegetative development under greenhouse conditions. In general, the development of grafted and non‐grafted plants was similar within a cultivar. The horticultural and pathological performances of the Galia‐type melons ‘Carrera’, ‘NUN‐5554’, ‘6003’ and ‘Arava’ were evaluated in experiments conducted in non‐infested and Monosporascus‐infested soils. In non‐infested soil, grafted and non‐grafted ‘Carrera’, ‘NUN‐5554’ and ‘Arava’ had the same yields. The yield of grafted ‘6003’ was significantly higher than that of its non‐grafted control. Responses of grafted and non‐grafted Galia‐type melons to Monosporascus cannonballus were evaluated and compared in the spring and autumn growing seasons. Significant differences in disease incidence were found among cultivars, between grafted and non‐grafted plants, and between growing seasons. Disease reduction and the beneficial effect of grafting on yield were more pronounced in the spring. The results indicate that Galia‐type melons can be grafted successfully, but the cultivation of the grafted plants should be adapted to each growing area and season.
