Dash - Range in reaction on each plant. Range in severity between plants but same reaction class. Natural Inoculum - Readings were made on flag leaf 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 VR & R = 0.2, MR = 0.4, MS = 0.8, and S = 1.0; t = 0.5.
