Bean yellow mosaic virus (BYMV) isolates from various locations in the USA and Europe could be classified in three distinct subgroups on the basis of serological and biological differences. Within each major subgroup were isolates that shared common host range and antigenic characteristics but which could be distinguished on the basis of numerous minor host range differences. Two of the BYMV subgroups appear to occur primarily in different natural hosts (red or white clover). A natural basis for BYMV subgroups would enable predictions about expected occurrence and severity in different leguminous crops.
