16 isolates of Fusarium culmorum obtained from Washington, North Dakota and Minnesota were tested for pathogenicity on five cultivars and lines: Chevron, CI 9549, Excel, Karl, Larker, Morex, Robust, M48, M66 and M69 were evaluated for reaction to the mixture of all isolates of the pathogen under field condition. The results of glasshouse test indicated that the isolates 10, 25 and 27 were the most virulent and isolates 11, 15 and 30 were the least virulent (P<0.05). Percentage of seed germination of M84-942 and M84-931 were 78.7% and 89.4%, respectively and were greater than those of CI 9539 (61%) and Chevron (66.3%) and that of Morex (46.8%) was significantly less than those of the others (P<0.05). The percentage of postemergence seedling blight in M84-942 (17.05%) was greater that those of the other cultivars and lines (P<0.05). Percentage of dry weight of roots in M84-931 and Chevron were 82.70 and 76.15, respectively and were greater than those of the others (P <0.05). The results of head blight test showed that Chevron had the least blight and percentage of necrotic spikelets in this cultivars was 3% and percentage of infected spikelets in CI 9539 and Morex were 18% and 19%, respectively and those of the other cultivars varied from 20% to 35%.
