*Yield adjusted to 10% moisture.
Sclerotina head rot, stalk rot, and downy mildew ratings
indicate percent of plants infected within a plot. Plants with head rot were not
harvested for yield. Plants with stalk rot were harvested but yields were
affected by timing of infection. Downy mildew infection was generally early and
no yield was obtained from most plants.
Midge rating at flowering indicates percent of ray petals
missing and is a measure of a hybrid's attractiveness to the midge. 0=no ray
petals missing. 9=all ray petals missing. Midge rating at maturity indicates
damage to the head and is a measure of a hybrid's tolerance to midge feeding.
0=no visible damage, 5=head completely closed with no seeds present.
