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).
Planted:	July 10, 2003.
Harvested:	November 11, 2003.
Seeding Rate:	140,000 seed/acre in 30" rows.
Soil Type:	Cecil coarse sandy loam.
Soil Test:	P = Medium, K = Medium, and pH = 5.9.
Fertilization:	Preplant:  28 lb N, 56 lb P2O5, and 84 lb K2O/acre.  Sidedress:  100 lb N/acre.
Previous Crop:	Soybean.
