Hello,

I would suggest you to read this article.

Article NC-42 and NC-43: Root-Knot Nematode–Resistant Cucumber Germplasm

Furthermore, have a look at "Genetics and genomics of cucurbitaceae" for a general overview of resistance screened in cucurbitaceae.

Following cultivars are resistant root-knot nematodes

Marketmore, Dynasty, Pioneer-II, and Summer Green,

there is no cultivar of cucumber resistant..:( Marketmore is highly susceptible as i have checked in greenhouse settings.

Cucumber cultivars may be different in susceptibility to root-knot nematodes, but as far as I know, by far, there are no cucumber cultivars resistant to root-knot nematodes, especially to Meloidogyne incognita.
