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 = 20.3% and df for EMS = 57.
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: April 25, 2001.
Harvested: August 17, 2001.
Seeding Rate: 100,000 seed/acre in 30" rows.
Soil Type: Dothan loamy sand.
Soil Test: P = Low, K = Medium, and pH = .6.1
Fertilization: Preplant:  54 lb N, 40 lb P2O5, and 60 lb K2O/acre.  Sidedress:  70 lb N/acre.
Previous Crop: Cotton.
Management: Moldboard plowed and rototilled; Aatrex and Prowl used for weed control; Nemacur used for
nematode control.
Test conducted by A. E. Coy, M. D. Pippin, R. E. Brooke, and T. L. Hancock.
