The research hypothesis assumes that Fusarium :culmorum infection affects the baking value of wheat. The aim of the research was to determine the effect of the cultivar on the rheological properties of wheat dough in response to Fusarium culmorum infection of wheat. A two-factor experiment conducted during the 2018&ndash:2020 growing seasons in Osiny, Poland, was set up using the completely randomized block design with three replications. The first factor was winter wheat cultivars (six cultivars), while the second factor was inoculation (two levels&mdash:Fusarium culmorum and distilled water&mdash:control). The immunoenzymatic ELISA method was used to determine the content of deoxynivalenol (DON) in grain. The DON content in the grain varied between cultivars. Fusarium culmorum inoculation resulted in an increase in protein, ash content, and flour water absorption, changes in dough rheological properties, and a decrease in the sedimentation index. Inoculation also caused negative changes in starch properties. The observed interaction between Fusarium culmorum inoculation and cultivars in shaping the qualitative parameters and rheological properties of the dough indicates that there are wheat cultivars less susceptible to Fusarium infection, which do not show any significant changes as a result of infection.
