Carrington-April 30 (flood-irrigation), Langdon-May 1. 1 = Comma - Separation of plants into two or more reaction classes (segregation or seed mixture). Dash - Range in reaction on each plant or range in severity between plants with the same reaction. Natural Inoculum - Additional inoculations of races 15(TLM), 15(TNM) and 151(QSH) at Fargo. t (trace) - equals less than 5% severity. Reactions - No visible infection (0), resistant (R), moderately resistant (MR), intermediate (M), moderately susceptible (MS), susceptible (S). Majority of the readings were made at soft dough.
