Abstract

Rhizoctonia root rot, caused by Rhizoctonia solani Kühn, is a soilborne disease that can cause yield loss in soybean (Glycine max). The soybean cultivar 'Savoy' has partial resistance to R. solani. 'Savoy' was crossed to 'Jack', a cultivar that is susceptible to R. solani. Progeny from this cross was evaluated in the greenhouse for reaction to R. solani. Reaction and segregation of the F₂ and F₃ generations to R. solani indicated that resistance behaves as a quantitative trait. Heritability estimates indicate that selection for resistance to R. solani in soybean based on F_2:3 family means would be more efficient than selecting on a single F₂ plant basis.
