Sudden death syndrome caused by highly pathogenic strains of Fusarium solani (Mart.) Appel & Wollenw. emend. Snyd. & Hans., can cause severe foliar necrosis and yield reduction in soybean [ Glycine max (L.) Merr.]. The soybean cultivar Ripley is resistant to foliar disease symptoms caused by F. solani . To determine the genetic control for F. solani resistance in Ripley, Ripley was crossed reciprocally to Spencer, a cultivar that develops severe foliar chlorosis and necrosis when infected with F. solani . Progeny from these crosses were evaluated in the greenhouse for reaction to F. solani using an infested‐oat inoculation technique. Reaction to F. solani in segregating F 2 and F 3 generations indicated that the ability for Ripley to resist foliar disease symptoms caused by F. solani is conditioned by a single dominant nuclear gene ( Rfs ).
