Relationship between grain yield and Fusarium head blight in soft red winter wheat as influenced by cultivar resistance
Abstract

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.
