Resistance to Fusarium head blight and deoxynivalenol accumulation in wheat.

An international collection of 116 wheat lines was evaluated for Fusarium head blight (FHB) resistance and concentration of DON in grain. Plants were inoculated with mixed isolates of F.graminearum in the greenhouse by injecting conidia into a single spikelet of each spike, and in the field by scattering F.graminearum – infected wheat kernels on the soil surface. Significant differences in FHB ratings and DON levels were observed among cultivars. Correlation coefficients were significant between FHB symptom ratings, seed quality traits and DON levels. Thus, the percentage of scabbed spikelets and kernels can be generally used to predict DON levels in harvested wheat grain.
