Days to bloom hybrid check: Hysun 311=79, SF270=77, PI6451=84
No hybrid reached visual physiological maturity before the October 1 killing frost.
No harvest moisture was recorded because of extended period of wet weather between killing frost and harvest. 
1Percent of plants that were infected with head rot and/or stalk rot.  The majority of stalk rot was mid-stalk rot. 
Differences between hybrids may have resulted from genetic differences and/or environmental conditons
that were more or less favorable for disease development during that hybrid's flowering period.
