Evaluation location: Utah, United States
Dwarf Bunt (causal fungus Tilletia controversa Kühn., TCK) incidence expressed as the number of infected spikes divided by the total number of spikes, reported as a percent of the susceptible check, average of two replications. Planted Sept. 24, 2019 on the Utah State University farm in Logan, Utah. Inoculated three weeks later with a composite of pathogenic races. Final rating took place on July 21, 2020. Differentials carrying Bt5, Bt8, Bt11, Bt12, Bt13, Bt14, Bt15, Btp and PI 173438 had DB incidence below 10% and were considered resistant. Differentials carrying Bt0, Bt1, Bt2, Bt3, Bt4, Bt6, Bt7, Bt9, and Bt10 had DB incidence =>10%. Wanser susceptible check entry averaged 74.1% incidence.
