Dash - Range in reaction of each plant. Range in severity between plant but same reaction class. Comma - Separation of plants into two or more reaction classes (segregation or seed mixture). Natural Inoculum - Readings were made on flag and flag minus one at milk to mid-dough stage. 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. Multiplication carried out for each reporting station and then an average is taken across stations. 1993 - Plants and rust evaluations were prime at all locations.
