The resistance of 90 European commercial winter wheat cultivars and advanced lines was tested after inoculation with common bunt. Out of it 27 cultivars/lines showed bunt incidence below 25% at least in one trial. The results obtained were compared with results published by other authors. Cultivars described as resistant were mostly resistant also in our trials. Of the cultivars registered in the Czech Republic cv. Globus proved to be highly resistant (bunt incidence 0–0.9%) followed by cv. Bill (bunt incidence 0.1–10.4%). Cultivar Tommi of similar pedigree as cv. Globus was highly resistant, too. The resistance of 21 North American and two European cultivars, sources of bunt resistance, was validated. The bunt incidence on 31 wheat cultivars tested in 2004 and 2005 was compared. Similar in both years was the ranking of the most resistant cultivars Globus and Bill. Cultivars Batis, Clever and Caphorn were very susceptible in both years; the ranking of medium resistant/susceptible cultivars varied. In all trials except in 1995 a mixture of Tilletia tritici and T. laevis was used for seed inoculation. In 1995 considerable differences in bunt incidence on several cultivars after separate inoculation with Tilletia tritici and T. laevis were found suggesting differences in virulence of the two bunt species in the trial.
