The virus-distribution and bimodal seed transmission of BCMV in bean cultivars was studied. BCMV was found to be seed transmitted in commercial seed lots of Phaseolus vulgaris L. cvs. Royal Nell (25.3%), Savana (13%), and Giza 4 (7.8%). Results showed that mechanically inoculated healthy seedlings (G0) showed typical symptoms of BCMV after 3-4 weeks from inoculation. ELISA test for Generation 1 (G1) detected the BCMV in all plant tissues tested except the cotyledon of cv. Giza 4 and the embryo of cvs. Savana and Giza 4. This finding points to the phenomenon of BCMV bimodal seed transmission.
