Evaluation of Soybean Cultivars for Production in Meloidogyne arenaria Race 2-Infested Soil.

Field trials with 56 soybean cultivars and breeding lines from public and private sources were conducted from 1986 through 1988 at a site infested with Meloidogyne arenaria race 2. Differences (P < 0.05) among yields were found each year and yields were negatively correlated (P < 0.01) with root-knot nematode galling. All entries were galled and the highest-yielding entries, 'Kirby' and 'Coker 6738', were determined to have average yield reductions of 56% and 62%, respectively, when compared with uninfested sites over the 3-year period.
