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 = 18.1% and df for EMS = 39.
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 5, 2000.
Harvested:	October 25, 2000.
Seeding Rate:	125,000 seed/acre in 30" rows.
Soil Type:	Cecil sandy clay loam.
Soil Test:	P = Medium, K = High, and pH = 6.4.
Fertilization:	Preplant: 28 lb N, 56 lb P2O5, and 84 lb K2O/acre. Sidedress: 100 lb N/acre.
Previous Crop:	Soybean.
Management:	Moldboard plowed and rototilled; Aatrex and one cultivation used for weed control.
Test conducted by P. A. Rose.
