1. Yields calculated at 13% moisture.
2. Lodging rating: Rated 1 (all plants erect) to 5 (over 80% of plants down).
3. Seed quality rating: Rated 1 (very good) to 5 (very poor).
4. CV = 13.0% and df for EMS = 12.
5. The F-test indicated no statistical differences at the alpha = .10 probability level; therefore a LSD value was not calculated.
6. CV = 7.8% and df for EMS = 18.
7. CV = 8.5% and df for EMS = 54.
Bolding within each test denotes entries with yields equal to the highest yielding entry based on Fisher's protected LSD (P = 0.10).
           
Planting dates: 6/4/98, 5/28/99, and 5/15/00 for Maturity Groups V & VI and 5/17/00 for Maturity Groups VII & VIII.
