1 Yields calculated as 50 lb/bu at 8.5% moisture.
2 Blackleg rated as total percentage of plants killed by blackleg or with severe basal stem canker.
3 Lodging rating: 1.0 = all plants erect to 5.0 = over 80% of plants down.
4 C.V. = 19.8%, and df for EMS = 72.
Bolding indicates entries yielding equal to highest yielding entry within a column based on Fisher's protected LSD (P = 0.10).
