1.  Yields calculated as 50 lb/bu at 8.5% moisture.
2.  2003 and 2001.
3.  Blackleg rated as total percentage of plants killed by blackleg or with severe basal stem canker.
4.  Lodging rating:  1.0 = all plants erect to 5.0 = over 80% of plants down.
5.  C.V. = 16.1%, and df for EMS = 69.
Bolding indicates entries yielding equal to highest yielding entry within a column based on Fisher's protected LSD
(P = 0.10).
