Fourteen of 630 plant introductions of wild soybean, Glycine soja, differed in resistance to bud blight caused by tobacco ringspot virus. Introduction 378 693-B in maturity group VII, a type with pubescent leaves and large seeds, was rated slightly resistant; 342 434 and 407 287, both in group V and having very small seeds, were rated moderately resistant and resistant, respectively. The other introductions selected were slightly resistant and had very small seeds. The nodule leghemoglobin content of these resistant introductions was equal to or greater than that of G. max cultivars. All the other introductions tested were susceptible.
