During growing season, 2011–2012, selected bean plant samples with symptoms of mosaic, vein clearing, leaf rolling, were collected from different part of Khorasan Razavi province of north-eastern Iran. To identify the virus, leaf samples were tested serologically by DAS-ELISA and tissue blot, using specific BCMV polyclonal antibody. Elisa positive samples were rechecked by RT-PCR and IC-RT-PCR using set of primers directed to the coat protein gene which were designed to detect and characterise the viral species. Similarly, the BCMV primers amplified product of approximately 373 bp in 1% agarose gel electrophoresis. In phylogenic analysis, A and B groups were formed for 12 Iranian isolate comparing with 18 BCMV isolates from GenBank. Iranian isolates were classified into three clusters indicating to have more homology 99.3% with Mexican Isolates. There are also indications of some diversities among Iranian BCMV isolates.
