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. 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 15 taken across stations.
