Scoring was done essentially according to the scaling of Parisi et al. (1993; year 2004) and to the descriptor Vi-F-2 as described by King et al. (1998; years 2005, 2006 and 2007). The different ranking letters between brackets refer to significant differences at the P = 0.05 level in an analysis of variance. The percentage of scab disease scores was calculated relative to the respective controls
aSantana did not show any symptoms and scored consistently a value of 0
