Dash - Range in reaction on each plant or range in severity between plants with same reactions. Natural Inoculum - Additional inoculation of races 15B (TIM), and 151 (QSH) at Fargo. Readings at soft dough to mid dough stages. Reactions - Resistant (R), moderately resistant (MR), intermediate (M), moderately susceptible (MS), susceptible (S). t = Equals less than 5% severity (percent of infection). Due to excessive drought - no stem rust readings were made at Minot.
