Abstract
Fusarium head blight (FHB) in wheat, caused by Fusarium graminearum (Fg), reduces yield and results in mycotoxin accumulation in the grain. Detached spikes from winter wheat varieties were inoculated with two Fg isolates and disease severity was estimated. Mycotoxin content of detached spikes was determined. Significant variety, isolate, and interaction effects were observed (p<0.001). FHB severity scores of varieties evaluated in an inoculated Fusarium nursery were correlated with those for detached spikes inoculated with a 3-ADON-producing Fg isolate. Results highlight the complex interactions between Fg isolates and wheat cultivars, indicating the need for further research to better understand these relationships.
