Two each of como (broad bean stain, BBSV; broad bean true mosaic, BBTMV) and potyviruses (bean yellow mosaic, BYMV; pea seed-bome mosaic, PSbMV) were seed transmitted by test fababean and vetch cultivars. Number of cultivars supporting seed transmission of BBSV (100%) were highest compared to those of BBTMV, BYMV and PSbMV (86%). Seed transmission levels of BBSV (3-20%) and BBTMV (0-28%) were higher than those of BYMV (0-17%) and PSbMV (0-11%) in these cultivars. Common bean cultivars were infected by BBSV (36%) and BYMV (9%) but not by BBTMV or PSbMV. In reactions of test common bean cultivars, the BYMV-fababean isolate was more similar to pea mosaic (PMV) than to other BYMV strains.
