Variability of components of fusarium head blight resistance among wheat genotypes

Fusarium head blight (FHB) is a serious threat for the quality of wheat products. In order to breed wheat lines with improved FHB resistance we investigated several FHB resistance components in Croatian and international wheat lines. We tested for Type I resistance (resistance against initial infection), Type II resistance (resistance against spreading), Type III resistance (DON resistance) and general FHB resistance. This information allows us to select proper parents used in future crosses to improve FHB resistance by combining and improving the level of individual resistance components. The genotypes Divana and SirbanProlifik showed the highest resistance levels against initial infection. The genotypes Libellula and Srpanjka had the highest resistance level against FHB spreading. The genotype Renan was the most DON resistant line.
