Figure 4

Ranking of the 34 potato varieties of the association panel according to the drought tolerance. Drought tolerance index (DRYM) of 34 potato varieties against rank of cultivar according to drought tolerance (DRYM) (1 most drought tolerant, 34 most sensitive). The bars at the bottom of the figure indicate the grouping according to the means comparison (REGWQ, α = 0.1). Cultivars that are underlined by the same bar are not significantly different in DRYM, e.g., 1 (most tolerant group) is different from 2 to 4 that belong into the second most tolerant group.
