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 = 6.8% and df for EMS = 60.
Bolding indicates entries yielding equal to highest yielding entry within a column based on Fisher's protected LSD (P = 0.10).
Planted: April 20, 1999.
Harvested: August 24, 1999.
Seeding Rate: 100,000 seed/acre in 30" rows.
Soil Type: Greenville sandy clay loam.
Soil Test: P = Medium, K = Medium, and pH = 6.1.
Fertilization: Preplant: 50 lb N, 70 lb P2O5, and 70 lb K2O/acre. Sidedress: 50 lb N/acre.
