**Yield and oil 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 represents 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.
