1. Yields calculated at 15.5% moisture.
2. Grain quality rating: 1 = excellent to 5 = poor.
3. Grain moisture at harvest.
4. Leaf Rust rating: 1 = resistant to 5 = highly susceptible.
5. Southern Corn Leaf Blight rating: 1 = resistant to 5 = highly susceptible.
6. CV = 12.4%, and df for EMS = 81.
7. 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).
