| * NOTE: Yields from the 1997 test at this site were extremely low due to prolonged drought. The editors have elected not to include these yields when calculating long-term averages due to their potential to excessively influence long-term variety averages. | ||||||||||
| 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 = 10.4% and df for EMS = 20. | ||||||||||
|
5. The F-test indicated no statistical differences at the alpha = 0.10 probability level; therefore an LSD value was not calculated. |

|
Bolding within each test denotes entries with yields equal to the highest yielding entry based on Fisher's protected LSD (P = 0.10). |
