Fusarium Head Blight (FHB) is a serious disease in all wheatgrowing areas in the world. FHB affects wheat by reducing yield and grain quality. Our objective is to characterize the relationship between FHB and grain yield. Three soft red winter wheat cultivars with different levels of FHB resistance (Truman, Hopewell and Cooper, moderately resistant moderately susceptible, and susceptible to FHB, respectively) were evaluated. Based on regression slopes, yield reduction per unit increase in FHB index varied among cultivars, being highest for moderately susceptible Hopewell, intermediate for moderately resistant Truman and lowest for susceptible Cooper.
