Evaluation of Soybean Cultivars for Production in Meloidogyne arenaria Race 2-Infested Soil
Abstract
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. Key words: Glycine max, Meloidogyne arenaria, root-knot nematode, soybean, resistance.Downloads
