Pathogenicity of seed transmitted<Emphasis Type="Underline">Fusarium</Emphasis> spp. to triticale seedlings

In the conducted studies 13 species ofFusarium were isolated into pure culture from triticale seed. Their pathogenicity was assessed under laboratory and greenhouse conditions. Most of the species studied were highly pathogenic to the first leaf see-dlings of triticale ‘Grado’ and ‘Lasko’ under both sets of conditions. It was shown, that seed-transmitted Fusarium spp. considerably reduced the ability of seeds to germinate and incited seedling blight. On average, triticale ‘Lasko’ was more resistant toFusarium spp. than ‘Grado’, but in some instances a reverse reaction was observed.
