Date of Planting 5-20-94 5-4-94 5-6-94
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.
1994 - Plants and rust evaluations were prime at all locations.
