Southern bean mosaic virus was recovered from immature embryos and seedcoats harvested from SBMV-infected Phaseolus vulgaris ‘Logan’. However, when the embryos and seedcoats were treated to remove surface contamination, infectivity was eliminated from the embryos, but not from the seedcoats. Virus infectivity was also recovered from decontaminated mature seedcoats.
