1. Blackleg rated as total percentage of plants killed by blackleg or with severe basal stem canker.
C Westar included as a susceptible check.
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: These nurseries were located on or 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.
Data collected by D. V. Phillips, C. B. Hill, L. Denmon, and D. Spradlin.
