Two experimental sets of selected winter wheat cultivars, breeding lines, old Czech and Slovak landraces and wheat wild relatives were infected with three isolates (R-116, UH-105, BR-331) of Mycosphaerella graminicola (anamorph Septoria tritici) isolated in the Czech Republic. Groups of cultivars with different disease severity to all three isolates of the pathogen were found. Differences between old Czech and Slovak landraces and wild wheat relatives were larger than between modern wheat cultivars and breeding materials. In experiment one the isolate BR-331 differed significantly from the other two isolates in virulence to the tested modern wheat cultivars and breeding lines. The method is considered as suitable for preliminary screening in wheat resistance breeding or phytopathological testing and as a complement to field tests.Keywords:
