1 = Dash - Range in reaction of each plant.
Natural Inoculum = Readings were made on flag and flag minus 1 at milk to
early dough stage.
C. 1. = 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.
Plants and rust evaluations were prime at all locations.
* = Data missing due to planting errors.
