The response of 22 winter wheat cultivars to artificial infection with Pyrenophora tritici-repentis has been studied in the field conditions for three years and in the greenhouse conditions as well. The set of cultivars included the cultivars registered in the Czech Republic and Swiss cultivar Arina known for satisfactory resistance to different foliar and head blights. High level of field resistance to Pyrenophora tritici-repentis was detected in cultivars Arina, Vlasta, Rialto, Athlet, Trane, Siria, Vega, Alana, Samara. Not all cultivars showed similar reaction in field and greenhouse tests. Correlation between results of the field and the greenhouse tests was significant for 18 of 22 cultivars. Arina, Vlasta and Vega showed acceptable field resistance and high resistance in the greenhouse tests to Pyrenophora tritici-repentis too. The greenhouse experiments helped to differentiate between examined isolates collected from the territory of the Czech Republic. Cultivar reaction to isolates No. 98001, 98007, 98010, 00071 correlated significantly with the field results.Keywords:
