Dash - Range in reaction on 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.
