Abstract
Ear rot in maize caused by Fusarium graminearum and/or F. verticillioides is a devastating disease resulting in contamination by several mycotoxins (deoxynivalnol, DON, zearalenone, ZEA, fumonisins, FUM). Significant (P=0.01) genetic variation for resistance to ear rot and mycotoxin content was found in both early and mid-late maturity groups of adapted European maize. The resistance reaction of the genotypes is highly dependent on environment, multi-environment testing is indispensable. F. verticillioides generally produces lower amount of disease compared to F. graminearum , however, the FUM contents are still substantial. High correlations between ear rot rating and DON and FUM concentrations, respectively, allow a prescreening on the basis of visual rating. For ZEA, the results still have to be verified in further experiments.
