Fifty three commercially grown cultivars and germplasm lines of winter triticale, wheat and rye and spring triticale, wheat and rye were inoculated at mid anthesis with a spore suspension consisting of a mixture of Fusarium culmorum, F. avenaceum and F. graminearum isolates of known toxigenic activity. Wheat suffered from the largest kernel weight reductions and accumulated the largest amounts of DON and 3 – acetyl DON in kernels. DON was not detected in grain samples of winter rye cv. Dankowskie Zlote and spring rye cv. Ludowe. 15 – acetyl DON was only detected in genotypes of triticale, and 3-acetyl DON only in a few genotypes o fwinter wheat and rye. MON was detected at low concentrations in kernels of some genotypes. A moderately strong Pearson correlation was found between head blight severity parameters and the accumulation of DON and its derivatives in grain of the cereal genotypes studied. Both Fusarium head blight resistant and susceptible genotypes of the three cereal species accumulated DON in kernels. This suggests that the system regulating DON accumulation may be independent of Fusarium head blight reaction.
