The inheritance of resistance to yellow mosaic virus spread by Bemisia taba
ci Gen. in Glycine soja (Linn.) Seib. & Zucc. was studied following natural
infection in the field condition. The resistant wild accession, Glycine so
ja was crossed with susceptible cultivars 'Ankur', 'Bragg', 'PK 472' and 'K
alitur' of Glycine max (Linn.) Merr. Resistance reactions of F-1 and F-2 pl
ants, and individual F-2 plant derived F-3 families indicated that resistan
ce was controlled by a single dominant gene.
