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 = 12.0% and df for EMS = 52.
6. CV = 24.8% and df for EMS = 32.
7. The F-test indicated no statistical differences at the alpha = .10 probability level; therefore, an LSD value
    was not calculated.
8. CV = 11.8% and df for EMS = 62.
Bolding within each tests denotes entries with yields equal to the highest yielding entry based on Fisher's
protected LSD (P = 0.10).
