*Yield and oil adjusted to 10% moisture. Oil percentages of NuSun Hybrids were not adjusted to NuSun oil percent.

Maturity hybrid check: days to flower for SF270=70

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 in the trial was quite severe. Plants generally were infected early and no yield was obtained from most plants.
