"Response to artificial infection with Fusarium culmorum and fungicide (metconazole or tebuconazole based) was studied in nine winter wheat cultivars that were in field experiments at the location Prague-Ruzyn\u011B for four years (2001-2004) evaluated for DON content in grain, pathogen DNA content (Ct) by real-time quantitative PCR, percentage of Fusarium damaged grains (FDG), symptom scores and reductions of grain yield components. All examined traits were highly affected by conditions of experimental years and interactions with cultivars and treatments. Moderately resistant cultivars Arina and Petrus were included in the first homogeneous group in all traits, including pathogen DNA content. To predict cultivar resistance to Fusarium head blight and accumulation of DON, examination for percentage of FDG in different environments appeared to be useful from practical aspects.
