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 = 10.0% and df for EMS = 58.
5.  The F-test indicated no statistical differences at the alpha = .10 probability level; therefore, a LSD value
     was not calculated.
6.  CV = 12.8% and df for EMS = 42.
7.  CV = 11.2% and df for EMS = 86.
Bolding within each test denotes entries with yields equal to the highest yielding entry based on Fisher's
protected LSD (P = 0.10).
