1.  Yields calculated at 14% moisture.
2.  Days from planting to 50% bloom.
3.  Rated 1 = resistant to 5 = susceptible to foliar diseases.
4.  Percent of grain head damaged.
5.  CV = 13.2% and df for EMS = 66.
6.  The F-test indicated no statistical differences at the alpha = .10 probability level; therefore, a LSD value was
     not calculated.
Bolding indicates entries yielding equal to highest yielding entry within a column based on Fisher's protected
LSD (P = 0.10).
