The suitability of 5 maturity group (MG) III and 5 MG IV soyabean cultivars as hosts for M. incognita and M. arenaria was evaluated in a greenhouse. Forrest, a MG V cultivar, was used as the standard of comparison for M. incognita resistance. With M. incognita, root-gall and egg-mass indices and reproductive factors for Asgrow 3307, FFR 398, and Pioneer 9442 were comparable with those found on Forrest. M. arenaria reproduction was lower on Stevens than on the other cultivars studied except TN4-86. When grown in a field infested with M. incognita, the relative ranking of the cultivars was similar to the greenhouse results.
