1.  Blackleg rated as total percentage of plants killed by blackleg or with severe basal stem canker.
C   Check variety.
Bolding indicates entries with blackleg resistance ratings equal to the best rated entry within a column based on Fisher's protected LSD (P = 0.10).
NOTE:  This nursery was located in the proximity of fields infected with Phoma blackleg the previous season.              Disease severity was further increased by spreading infected stubble over the nursery shortly after              planting.
