A seed-borne virus disease of peas described in Washington, Oregon, and Wisconsin was found to be related serologically to pea seed-borne mosaic virus described in Japan. The discrepancies among particle length measurements reported for the U.S. and Japanese isolates appear to be due to methods which were used to prepare the U.S. isolates for electron microscopy.
