Significant differences
between Jerusalem artichoke genotypes were observed for percent
disease incidence and days to permanent wilting. Interaction of
genotype T. harzianum (G T), T. harzianum G. clarum (T M),
and genotype T. harzianum G. clarum (G T M) were also
highly significant for these traits. HEL 246 had lower disease incidence
(59.4%) than JA 37 (75.6%),
