Dash - Range in reaction of each plant. Range in severity between plant but same reaction class. Natural inoculum - Readings were made on flag and flag minus 1 at milk to mid dough stage. 2 = C.I - Average Coefficient of infection. Percent severity multiplied by the following values for reaction types: R = 0.2, MR = 0.4, MS 0.8, S = 1.0, t = 0.5. Multiplication carried out for each reporting station and then an average is taken across stations. Stem rust was heavy at Fargo and may have influenced leaf rust evaluations.
