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 = 17.7% and df for EMS = 54.
5. The F-test indicated no statistical differences at the alpha = .10 probability level; therefore a LSD value was not calculated.
6. CV = 10.5% and df for EMS = 36.
7. CV = 17.5% and df for EMS = 126.
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: 7/7/98, 6/25/99, and 6/5/2000.
