Common bunt caused by Tilletia caries is one of the most devastating diseases of wheat, especially in organic farming. Growing of resistant varieties is the best way to reduce the spread of common bunt. The aim of the present study was to determine the incidence of common bunt depending on variety by using artificial infection. The experiments were carried out at the Stende Research Centre (SRC) of Institute of Agricultural Resources and Economics (AREI). A two-factor experiment in three replications was established: factor A – inoculation (inoculated and non-inoculated seeds); factor B – six varieties. Four varieties bread by SRC, and two widely cultivated varieties were used. The infection was done by mixing the seeds with the spores of Tilletia caries (0.05 g of spores per 90 seeds). Seed germination and seedling overwintering was not influenced by infection. Common bunt was not observed in non-inoculated variant, but in the inoculated variant, the incidence of common bunt varied from 3 to 71% depending on variety. Further studies are required because the one-year results do not allow to evaluate the resistance of cultivars.
