Components of Fusarium head blight (FHB) caused by Fusarium spp were examined in one Chinese and seven New Zealand wheat cultivars and in 141 doubled haploid lines from a cross between a susceptible and a moderately resistant cultivar Components measured were incidence of FHB proportions of grains with visible FHB infection mycotoxins levels in grain and proportion of grains infected with Fusarium Lines were sown in a field trial that was inoculated with F graminearum and mist irrigated to enhance infection The Chinese cultivar Nanjing had the lowest level of FHB in ears and visibly infected grains and Fusarium infection in harvested grain Two New Zealand cultivars also had low levels of FHB components while two other cultivars had medium levels and three had high levels of infection There were moderate to good correlations between most components of FHB except that the proportions of visibly infected grains were poorly correlated with other components
