1 = Comma- Separation of plants into 2 or more reaction classes (segregation or seed mixture)
Dash - Range in reaction on each plant or range in severity between plants with the
same reactions.
Natural inoculum - Additional inoculations of races 15B and 151 at Fargo. Readings at soft
dough to mid dough stages.
2 = Av. C.I. Average coefficient of infection. Percent severity multiplied by the following
values for reaction types: VR & R = 0.2, is the average of the 5 coefficients of infection for
each entry. Coefficient of infection
M = Missing plants.
