Technical Abstract: Microplot experiments were conducted over two years (four growing seasons) to evaluate Meloidogyne incognita resistance in rootstocks used for grafted tomato (Solanum lycopersicum), muskmelon (Cucumis melo), and watermelon (Citrullus lanatus). Three tomato rootstocks; ‘TX301’, ‘Multifort’, and ‘Aloha’, were tested in addition to the nongrafted scion, ‘Florida-47. Two muskmelon rootstocks; Cucumis metulifer and ‘Tetsukabuto’ (Cucurbita maxima x Cucurbita moschata) were evaluated with the nongrafted scion ‘Athena’. Two watermelon rootstocks included ‘Emphasis’, a lagenaria-type, and an interspecific squash hybrid ‘StrongTosa’, which were grafted to the scion ‘TriX Palomar’ and planted only in the second year. M. incognita eggs were applied to microplots in September each year. Tomatoes were planted in September followed by melons in March. In tomato, M. incognita juveniles in soil were similar among all tomato rootstocks, but numbers in roots were higher in the nongrafted Florida 47 than in all grafted rootstocks in both years of the study. In muskmelon only C. metulifer rootstock reduced galling in nematode infested soil. Tetsukabuto did not perform well in reducing numbers of M. incognita juveniles in either soil or roots either year. There were no differences in nematode numbers, galling, or plant growth parameters measured among the watermelon rootstocks tested.
