Results correspond to the combination of Disease Rate (based on a 0–5 scale, Roger and Tivoli 1996) and the % of the whole plant covered by symptoms (% Disease Severity, DS %) as follows:
++++, highly susceptible (DR ≥ 3 and DS > 35%); +++, susceptible (DR ≥ 3 and DS < 35%); +, moderately resistant (2 < DR < 3 and DS < 35%); –,highly resistant (DR < 2 and DS < 10%).
*
When several classifications are reported means that genotypes from the same specie showed different responses to the same fungal isolate. Classification reported in first position is the most common.
