A virus associated with rice mosaic (RMAV) in certain rice fields of Fars and Kohkiluyeh and Boyrahmad is morphologically similar to Iranian maize mosaic rhabdovirus (IMMRV). The two viruses were compared serologically and in regard to host range. In greenhouse experiments, RMAV was transmitted to rice, barley, wheat (Triticum aestivum), corn, barnyardgrass (Echinochloa crus- galli), and goosegrass (Eleusine indica) seedlings. The infected sap of these plants reacted positively with IMMRV antiserum in DAS- ELISA test. In host range studies, non- viruliferous planthoppers (Laodelphax striatellus), after an acquisition access period of 7-10 days on maize or barley infected with IMMRV or the rice virus, respectively, were transferred to seedlings of a number of grasses under greenhouse conditions. The two viruses infected wheat (Triticum aestivum), turgidum wheat (T. turgidum), durum wheat (T. durum), sorghum (Sorghum bicolor), green foxtail (Setaria viridis), barnyardgrass (E. crus- galli and E. colonum), and millet (Panicum miliaceaum). The main symptoms of infection were mosaic in leaves and dwarfing of plants and sometimes denticulation of leaf margins
