Effect of plant height on Fusarium head blight in spring wheat.

Fusarium head blight (FHB), caused by the fungal species Fusarium graminearum, is a disease affecting wheat cultivars across Canada. Recent and severe outbreaks have spurred research in developing FHB-resistant cultivars and evaluating the underlying causes of FHB susceptibility. The effect of plant height on Fusarium Head Blight in Canadian spring wheat was evaluated over a period of two years in this study. Cultivars of spring wheat varying in origin, height, and disease susceptibility were artificially inoculated with FHB, and the subsequent disease symptoms and height were noted. It was found that plant height is negatively correlated with FHB incidence and severity. However, varieties originating from Eastern Canada had a much stronger negative correlation between plant height and FHB, whereas the trials with Western Canada origins were weakly correlated.
