 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 = 0.4, MS = 0.8, S = 1.0, t = 0.5.
