Abstract

Mycotoxins are secondary metabolites of very different chemical structure with different biological effects. Depending on the Fusarium species in grains we can expect mycotoxins: zearalenol, deoxynivalenol (F. graminearum), T-2 toxin, neosolaniol, scirpenol (F. avenaceum), T-2 toxin, HT-2 toxin, tetraol (F. poae) . The aim of this paper is to present the variability of wheat genotypes with an estimated amount of DON based on symptoms of disease assessed at 22nd day after artificial infections. The lowest estimated amounts of DON in genotypes were calculated for Renan (0.8 mg/kg), Soissons (1.0 mg/kg), Sirban Prolific (1.3 mg/kg) and Libellula (1.5 mg/kg), and the highest in Osk.553/98 (7.5 mg/kg), Osk.554/97 (7.1 mg/kg), Žitarka (6.4 mg/kg) and Zlatna Dolina (5.8 mg/kg).
