Resistance in soybean [ Glycine max (L.) Merr.] root‐knot nematodes is a valuable control measure for reducing losses to this pathogen. Screening only in the field has the disadvantages of seasonal restrictions and lack of uniformly infested soil. The objective of this study was to develop a simple and reliable greenhouse screening procedure. Root‐knot nematode [ Meloidogyne incognita (Kofoid and White) Chitwood] eggs were grown under supplemental light in the greenhouse. Experiments were conducted comparing different genotypes, inoculum densities, and nematode collections. The similarity between the responses of genotypes to M. incognita in the greenhouse and in field tests indicated that this procedure provides a reliable evaluation of the reaction of soybean to this nematode.
