Comparison of biomass and deoxynivalenol production of northern European and southern European Fusarium graminearum isolates in the infection of wheat and oat grains

Abstract The 3ADON chemotype of Fusarium graminearum predominates in northern Europe, whereas the 15ADON is predominant central and southern Europe. Therefore, it has been suggested that there are two F. populations which may have specialized to different host plants. aim present work was test this hypothesis by comparing European isolates (15ADON chemotype) from Russia (3ADON Finland infection grains wheat cultivar Wellamo oat Venla. biomass levels were measured TaqMan (2018) SYBR Green (2019) qPCR, while DON chromatographic methods. Most qPCR results supporting more than Finland. In oat, not as clear differences between isolates, but 2018 higher DNA 2019 found samples inoculated with isolates. Our line literature according also highest Europe they maize.
