Comma - Separation of plants into two or more reaction cla55es (segregation or seed mixture). Dash - Range in reaction of each plant. Range in severity between plant but same reaction class. 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.
