Comma = Separation of plants into 2 or more reaction classes (segregation or seed mixture). Dash = Range in reaction on each plant. Natural Inoculum - Readings were made on flag and flag leaf minus 1 at milk to soft dough stages of growth. 2 = Average coefficient of Infection (Avg. C.I.). C.I. was calculated by multiplying percent severity by reaction where 0=0.0, R=0.2, MR=0.4, MS=0.8, and S=1.0. Avg. C.I. equals all C.I.s for an entry added and divided by the number of locations.
