| 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 = 19.4% and df for EMS = 69. | |||||||||
| 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). |
