Comparison of visual head blight ratings, seed infection levels, and deoxynivalenol production for assessment of resistance in cereals inoculated with Fusarium culmorum.

Seven spring wheat, 13 barley, 14 oats and 20 winter wheat genotypes were inoculated at flowering with mixed conidial suspensions of 8 isolates of Fusarium culmorum.  Four weeks after inoculation, head blight was recorded in the field.  After harvest, seed infection was assessed by a Freezing Blotter Test in the laboratory.  Seed samples were also analysed for DON content.  Highly significant correlations were found between the percentage of heavily infected seed and the DON content.  The weighted mean value of infected seeds and DON content were also significantly correlated.  No significant correlation was found between head blight rating in the field and DON content.
