The objective of our study was to determine the changes in deoxynivalenol (DON) concentrations in barley and malt in function of the year and variety, and to define the relation between these concentrations and some technological parameters. Three barley varieties (Akcent, Kompakt, Forum) were intentionally inoculated with Fusarium culmorum in field trials carried out during the years 2000-2002. DON concentrations in the barley as well as in the malt varied considerably according to the year, variety and forecrop (sugarbeet or wheat). In some of the samples DON concentrations were significantly higher in the malt than in the corresponding barley. The forecrop, barley variety and year influenced also oxalate concentrations and gushing. In conclusion, the variety Forum was the most suitable for malting, while the variety Akcent was the least suitable.
