| 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. Shattering rating: Rated 1 (no shattering) to 5 (>50% pods shattered). | |||||||||
| 5. CV = 24.2% and df for EMS = 10. | |||||||||
| 6. The F-test indicated no statistical differences at the alpha = .10 probability level; therefore, a LSD value was not calculated. | |||||||||
| 7. CV = 20.4% and df for EMS = 20. | |||||||||
| 8. CV = 16.3% and df for EMS = 18. | |||||||||
| Bolding within each test denotes entries with yields equal to the highest yielding entry based on Fisher's protected LSD (P = 0.10). | |||||||||
