Summary This work aims to determine dependencies of single‐kernel (SK) physical traits on the kernel degree of fusariosis. The measurements were taken on samples of grain of six wheat varieties cultivated during 1–3 years. For SK mass, volume and width this dependence resulted in lowered (by at least ten to more than 25% for mass and volume, and ca. 5 to more than 15% for width) values in Fusarium culmorum infested grain as compared with the non‐inoculated control. In addition, moderately infested kernels tended to be of higher mass and size than kernels with no symptoms of infestation. An unexpected effect was a lack of dependence of SK density on the degree of infestation. Moisture content was lower for infested kernels by 6–8%, hardness tended to increase a little for moderate infestation, while it noticeable decreased for the heaviest infestation.
