*  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 = 15.5%, 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:	March 27, 2003.
Harvested:	August 18, 2003.
Seeding Rate:	28,000 seeds/acre in 30" rows.
Soil Type:	Faceville sandy loam.
Soil Test:	P = Medium, K = High, and pH = 6.1.
Fertilization:	120 lb N, 80 lb P2O5, and 80 lb K2O/acre as preplant; 150 lb N/acre as sidedress.
Previous Crop:	Soybean.
Management:	Subsoiled and rototilled; Prowl, Atrazine and one cultivation used for weed control; irrigated 7.0 inches.
Test conducted by A. E. Coy, M. D. Pippin, R. Burton, R. E. Brooke, J. L. Day, and R. R. Pines.
