Powdery mildew (PM) Varieties were evaluated for Powdery mildew at Wooster at the heading (Feekes growth stage 10.5) growth stage.
Fusarium Head Blight (FHB) Varieties were evaluated in an inoculated disease screening nursery at Wooster. FHB was rated as the percentage of spikelets showing diseased symptoms.
Leaf Blotch (SLB) and Glume Blotch (SGB) Varieties were evaluated for Stagonospora leaf and glume blotch in an inoculated, mist-irrigated disease screening nursery at Wooster. Both SLB and SGB severity were rated at about Feekes growth stage 11.3 as the average percent flag leaf and spike area diseased, respectively.
All varieties were classified as Susceptible, Moderately Susceptible, Moderately Resistant and Resistant based on their disease scores relative to susceptible and resistant checks. It must be noted that there is no true resistance to these diseases. For instance, an R for FHB (head scab) means that the variety had comparable levels of scab to Truman, the resistant check.
