In the last decade two mastreviruses, Wheat dwarf virus (WDV) and Oat dwarf virus (ODV) have been reported from cereal farms in Iran. In a survey, wild and cultivated hosts of these mastreviruses were studied during 2015 to 2017. Symptomatic small grain cereal samples and weed species were collected and assayed for WDV and/or ODV infection by PCR. While WDV which was detected in 139/284 (49%) of total symptomatic samples, low incidence (2%) was recorded for ODV which was detected only in slender wild oat (Avena barbata Pott ex Link) and red brome (Bromus rubens L.). In agroinfection studies, the clone of ODV infected common oat (A. sativa) and slender wild oat (A. barbata) with the low efficiency and did not infect wheat or barley. ODV was transmitted by the leafhopper Psammotettix alienus, from agroinfected common oat to healthy seedlings. The results show that, in contrast to WDV, ODV has a low incidence and a narrow host range in gramineous plants.
