Figure 1.

Potato cultivars show variation in waterlogging tolerance. Relative shoot dry weight (a), relative leaf area (b) of 6 elite potato (S. tuberosum) cultivars during 12 days of waterlogging. Values are relative to non-waterlogged plants who were set at 100% per time-point (a,b). Asterisks indicate significant differences between the Festien (purple) and Seresta (pink) cultivars per time-point and these were the cultivars selected for further analysis (indicated by arrows, ** p < 0.01, Generalized linear model, Tukey’s honestly significant difference (HSD), n = 10 plants).
