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).
Data collected by D. V. Phillips and D. Spradlin.
 
NOTE: This nursery was located adjacent to fields infected with Phoma blackleg the previous season. Disease severity was further increased by spreading infected stubble over the nurseries shortly after planting.
