*  Full-season hybrid.
1.  Yields calculated at 15.5% moisture.
2.  Grain quality rating:  1 = excellent to 5 = poor.
3.  Grain moisture at harvest.
4.  Leaf Rust rating:  1 = resistant to 5 = highly susceptible.
5.  Southern Corn Leaf Blight rating:  1 = resistant to 5 = highly susceptible.
6.  CV = 6.8%, and df for EMS = 51.
7.  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:	April 4, 2003.
Harvested:	August 15, 2003.
Seeding Rate:	27,000 seeds/acre in 30" rows.
Soil Type:	Tifton loamy sand.
Soil Test:	P = Medium, K = Medium, and pH = 6.7.
Fertilization:	25 lb N, 50 lb P2O5, and 75 lb K2O/acre as preplant; 122 lb N/acre as sidedress.
Previous Crop:	Soybean.
Management:	Paratilled, subsoiled and bedded, rototilled; Prowl, Atrazine, Permit, and Accent used for weed control;  Telone II used for nematode control.
