1. Yields calculated at 13% moisture.
2. Lodging rating: Rated 1 (all plants erect) to 5 (over 80% of plants down).
3. Seed quality rating: Rated 1 (very good) to 5 (very poor).
4. Shattering rating: Rated 1 (no shattering) to 5 (>50% pods shattered).
5. CV = 16.4% and df for EMS = 28.
6. The F-test indicated no statistical differences at the alpha = .10 probability level; therefore, a LSD value was not calculated.
7. CV = 21.4% and df for EMS = 34.
8. CV = 11.8% and df for EMS = 20.
Bolding within each test denotes entries with yields equal to the highest yielding entry based on Fisher's protected LSD (P = 0.10).
Planted: May 11, 2000.
Harvested: Maturity Group V - October 23, 2000.
  Maturity Group VI - October 16, 2000.
  Maturity Groups VII & VIII - October 26, 2000.
Seeding Rate: Eight viable seeds per foot in 30" rows.
Soil Type: Tifton loamy sand.
Soil Test: P = High, K = Medium, and pH = 5.9.
Fertilization: 14 lb N, 42 lb P2O5, and 84 lb K2O/acre.
