Small-plot field trials were conducted to study the reactions of 13 registered winter barley varieties to infection with the wheat dwarf virus (WDV). The varieties were artificially infected with a barley strain of WDV at the tillering stage in the autumn. All studied varieties reacted with strong symptoms of plant stunt, heading disorders, leaf yellowing, reduced aboveground biomass production and grain yield depression. There was no resistant variety among the tested cultivars. The varieties Agrilo, Marinka, Kromir, Kromoz, Okal and Sigra with grain yield depression of more than 90 % were classified as very susceptible. The other varieties, Babylone, Borwina, Kamil, Lunet, Luxor, Marna and Monaco, were classified as susceptible with grain yield depressed by 79.2 % to 88.7 %.
