Reactions O = no visible symptom; R = resistant; MR = moderately resistant; MS = moderately susceptible, S = susceptible. Readings were made at 60ft dough stage of growth. Natural inoculum plus additional inoculum from inoculations of race 15(TLM), 15(TNM), 151(QFB) and 151(QSH) at Fargo. Comma = Separation of plants into 2 or more reaction classes (segregation or seed mixture). Dash = Range in severity between plants with the same reactions.
