In greenhouse trials, receptivity to oat blue dwarf virus (OBDV) of 48 monocotyledonous and dicotyledonous plant species was proved. Most host plants responded to the virus infection with characteristic symptoms, while the disease was latent in only two dicotyledonous species. Back transmission of the virus to oat seedlings was carried out with selected species. Among the receptive species, 39 newly identified and hitherto unreported OBDV host plants were found among the following genera: Aegilops, Anthoxanthum, Avena, Bromus, Cichorium, Hordeum, Lagurus, Lolium, Phalaris, Plantago, Poa and Triticum. Virological analysis of plant samples collected in the field showed that the range of natural OBDV host plants also included Avena fatua, Bromus arvensis, Hordeum murinum, Lolium multiflorum, L. perenne, L. temulentum, Poa annua, Plantago major, Linum usitatissimum and Stellaria media.
