Abstract

The purpose of this study was to determine the variability of resistance to root-knot nematodes (Meloidogyne incognita) in soybeans (Glycine max) induced by seed. treatment with ethylmethane sulfonate (EMS). Two soybean varieties, 'Essex' and 'Forrest,' were chosen as the experimental materials mainly on the basis of their distinct level of resistance; 'Essex' is susceptible and 'Forrest' is resistant. The M2 and control populations were grown and tested for nematode resistance in the greenhouse. The number of galls developed on the roots was used to indicate the level of resistance.
