Popis:	Fusarium graminearum is the principal cause of fusarium head blight in North America, a disease that has caused severe losses in yield and quality of cereals. In North America, the vast majority of F. graminearum isolates produce 3- or 15-acetyl deoxynivalenol (ADON) in addition to DON. Until recently, 15-ADON isolates predominated, but a rapid shift from 15-ADON to 3-ADON producers in Canada and north central USA has been documented. In order to better understand the effect of this population shift on relative aggressiveness of isolates and mycotoxin accumulation, we tested a total of 58 isolates for 3- and 15-ADON production on two Canadian spring wheat cultivars, ‘Roblin’ (susceptible) and ‘5602 HR’ (moderately resistant). In Experiment 1, three isolates from the Canadian provinces of Manitoba, Saskatchewan and Alberta, each of which produced either 15-ADON or 3-ADON, were tested using spray inoculation. In Experiment 2, 20 isolates which produced 15-ADON and 20 which produced 3-ADON from Mani...
