Evaluation location: Niederösterreich, Austria
Common bunt (causal fungus Tilletia caries) incidence expressed as the number of infected spikes in 75 randomly chosen spikes per plot, reported as percent of the susceptible check, data from an unreplicated trial. Planted Nov. 15, 2021 on the BOKU experimental site in Tulln, Austria. Inoculated prior to sowing with a spore suspension of common bunt teliospores in a mixture of methylcellulose in water (2g of methycellulose for 1000mL of water). A composite of common bunt races prevalent in eastern Austria was used. Scoring took place between June 23 and July 21, 2019. Differentials carrying Bt1, Bt3, Bt4, Bt5, Bt6, Bt10, Bt11, Bt12, Bt13 and Bt14 had CB incidence below 10% and were considered resistant. Differentials carrying Bt0, Bt2, Bt7, Bt8, Bt9, Bt15 and BtP had CB incidence =>10%. Differential Bt7 was not available in 2021. Capo as the susceptible check entry averaged 61.95% incidence.
