| 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 = 12.8% and df for EMS = 63. | |||||||||
| 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). | |||||||||
