Dash - Range in reaction on each plant or range in severity between plants with same reactions. Natural inoculum - Additional inoculation of races 15B(TLM,TNM) and 151(QSH) at Fargo. Readings at soft dough to milk stages. Reactions - No visible infection (0), resistant (R), moderately resistant (MR), intermediate (M), moderately susceptible (MS), susceptible (S). t (trace) - Equals less than 5% severity percent of infection.
