Barley stripe mosaic virus (BSMV) was found in seeds of 24 varieties originated from barley cultivar collections per 40 tested. The virus more frequently occurred in seeds of winter cultivars where it was detected in seeds of 17 varietes per 19 tested while in seeds of spring cultivars it was found only in 7 cultivars per 21 tested. Similar results were obtained in the case of commercial varieties. The infection of seeds of some varieties exceeded 10%. In all cases occurrence of the mild and no symptoms was confirmed. Preliminary studies showed that BSMV caused the decrease of yield by 9–15% and the decrease of mass of 1 000 seeds ranging from 0.5 to 3%. The risk of isolate mutation of a mild BSMV to the isolate causing severe symptoms was observed in spring barley cultivar Annabell.
