The Fungal Communities on Spring Wheat Seeds From Different Environmental Conditions

Seeds of ten cultivars of spring wheat from five different localized breeding stations were tested for seedhealth. The same seeds were sown in Radzików in field experiment and its seed health after harvest was evaluatedalso. The basic material of wheat was infected by numerous fungi: 36 fungal species belonging to 24genera and the most often occurred: Alternaria alternata, Epicoccum purpurascens, Fusarium spp.,Drechslera spp. and B. sorokiniana. It was found significant differences between cultivars for total fungioccurred on seeds, for seed infection by main pathogens (B. sorokiniana, Drechslera spp. and Fusariumspp.). Also seeds from breeders were strongly infected by these pathogens in comparison to seeds harvested infield experiment in Radzików.
