¹Area under disease progress curves of lesion size of chocolate spot in the whole plant test.
²Linear lesion size expansion rates were estimated as the slope of linear regression of the following function: Lesion diameter = a + Lesion growth rate x time (based on untransformed data).
** The presence of highly significant difference at P<0.05 probability level.
Means of lesion sizes and AUDPC in the same column followed by the same letters are not statistically different (P<0.05). Values are based on untransformed data.
