Evaluation location: North Dakota, United States
Accessions were tested under greenhouse conditions by inoculating three-week old seedlings. Individual plants were inoculated with rust races 1-4 using the Q-tip method. Plants were evaluated using the classical rust severity scale of `0-4'. Pustules classified as 0, 1 or 2 were categorized as resistant and type 3 and 4 pustules were lumped into the susceptible category.
