*Comma - Separation of plants into two or more reaction classes (segreg
ation or seed mixture).
Dash - Range in reaction of each plant. Range in severity between plant but
same reaction class.
Natural inoculum - Readings were made on flag and flag minus I 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.
