Root‐knot nematode,Meloidogyne incognita(Kofoid and White, 1919) Chitwood, 1949, Race 1, is widely distributed in agricultural soils of northern Nigeria and has been shown to limit production of various commonly grown crops such as tomato, chilli, okra, cowpea, yam, rice etc. Certain cultivars of maize (Zea maysL.), the third most important cereal crop in Nigeria after rice and sorghum, have been found to be resistant to this nematode in varying degrees elsewhere in the world. In the absence of any such information in Nigeria, 30 cultivars of maize were tested for their reaction to the infection of this nematode under screenhouse conditions and all were found to be resistant and, therefore, suitable for inclusion as poor or nonhosts in any crop rotation programme.
