Selected soybean genotypes were evaluated for resistance to North Carolina populations of the soybean cyst nematode Heterodera glycines, the root-knot nematodes Meloidogyne incognita races 3 and 4, M. arenaria races 1 and 2, M. javanica, and the reniform nematode Rotylenchulus reniformis in two greenhouse tests. Populations of cyst nematode used in the first test were cultures from field samples originally classified as races 1-5, and those used in the second test included inbred cyst lines that corresponded to races 1, 3, and 4. The original race classification of some cyst populations shifted after repeated culture on susceptible 'Lee 68' soybean. Most of the cyst-resistant soybean cultivars tested were susceptible to M. arenaria and M. javanica. Exceptionally large galls were induced by M. arenaria on roots of Asgrow 5979, Hartwig, and CNS soybean. Hartwig soybean and PI 437654 were resistant to all cultured field populations of cyst nematodes in a first greenhouse test. In the second test, cyst indices of 11.3% and 19.4% were observed on roots of PI 437654 and Hartwig, respectively, when infected with an inbred line (OP50) of H. glycines corresponding to race 4. The cyst-resistant soybean germplasm tested, including Hartwig and PI 437654, supported only low numbers of reniform nematodes. The most severe soybean root necrosis observed, however, was associated with reniform nematode infection.
