Fig. 2.

The results of the redundancy analysis of the effect of ploidy level (2x, 4x) and plant origin (natural, synthetic) on plant performance. The variables flowering (yes/no) and fruiting when flowering (yes/no) are not shown due to their low variation in the analysed sub-set of the data (see the Materials and Methods for details). The first (horizontal) axis explains 10·4 % and the second (vertical) axis explains 4·4 % of the total variation in the data set. The effect of plant origin and ploidy level is significant (Table 4).
