Results of the tests for bunt resistance of the cultivars registered in the Czech Republic and older Czech and Slovak cultivars carried out from 1988 to 2005 are presented. In most experiments mixture of samples of T. tritici and T. laevis from different locations was applied for inoculation. In 1995 samples of above mentioned species were used separately. Of the older Czech and Slovak cultivars Roxana, Dobrovicka přesivka, Hela, Mara and Vala showed high to medium resistance. Of the registered cultivars the highest resistance was displayed by the German cv. Globus and Danish cv. Bill, followed by the Czech cv. Niagara. Ranking of cultivars tested in 2004 and 2005 varied, except the most resistant cultivars Globus, Bill and Niagara.
