Differences in the rates of soybean mosaic virus seed transmission among cultivars and lines of soybean, Glycine max (L.) Merr., were determined by double antibody sandwich enzyme-linked immunosorbent assay of seedlings. The presence of soybean mosaic virus in 5- to 6-wk-old soybean seedlings varied significantly among 11 cultivars and lines. The virus was detected in plants grown from mottled and nonmottled seeds, but the difference was not significant. Virus-infected plants grown from mottled seeds produced 71.5% mottled and 28.5% nonmottled seeds. Virus-free plants grown from mottled seeds produced 65.2% mottled and 34.8% nonmottled seeds. Virus-infected plants grown from nonmottled seeds produced 81.9% mottled and 18.1% nonmottled seeds. Virus-free plants grown from nonmottled seeds produced 70.8% mottled and 29.2% nonmottled seeds. Mottling of soybean seeds was not indicative of the presence of soybean mosaic virus in plants grown from these seeds or of the incidence of mottled seed produced by these plants.
