1.  Yields calculated at 14% moisture.
2.  Days from planting to 50% bloom.
3.  Rated 1 = resistant to 5 = susceptible to foliar diseases.
4.  CV = 10.6% and df for EMS = 75.
Bolding indicates entries yielding equal to highest yielding entry within a column based on Fisher's protected
LSD (P = 0.10).
