A literature study has been carried out about resistance and tolerance of cucumber and sweet pepper rootstocks to Meloidogyne spp. and Verticillium dahliae. This study offers an overview of research in practice and international scientific literature. For cucumber no rootstocks are known that are resistant to M. incognita. However rootstocks are available that have a high tolerance and a lower development of eggs and galls on the roots. Within Cucumis sativus especially hardwickii species have a high tolerance for a broad range of nematodes, but not to M. incognita. Tolerance to this nematode is found in related species of cucumber; Sycios angulatus ‘Harry’, Cucumis metuliferus and Cucurbita spp. The thin stem of Hardwickii and Cucumis metuliferus compared to cucumber complicates grafting. For sweet pepper resistance to M. javanica is present within Capsicum anuum and also within other Capsicum species. To M. incognita only partly resistant rootstocks are available. These species are listed in this study. Within Cucurbitaceae resistance is known to Verticillium dahliae, likeCucurbita ficifolia. Disadvantages are the lower production of cucumber grafted on these rootstocks and/or the lack of resistance to other pathogens like Phomopsis sclerotioides. For sweet pepper species are found with a high tolerance to Verticillium dahliae, but not with complete resistance. Especially ‘Snooker’, ‘Padron’ and ‘Yolo Wonder’ are tolerant. ‘Luesia’, ‘Podarok’ and P1201234 are quite tolerant.
