1 = Comma: Separation of plants into two or more reaction classes (segregation or seed
mixture). 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=0.04, MS=O.8, s=1.0, t=0.5.
