Fig. 3. Multidimensional scaling representation of the Spearman rank correlation coefficients obtained from the between-groups correlation matrix (Fig. 3a) and the within-group correlation matrix (Fig. 3b), for 15 variables (trait–environment) of the groups obtained from the evaluation of 256 Caribbean maize accessions planted in three environments (data set 1). Traits are ear length (EL), plant height (P), days to senescence (DS), days to anthesis (DA), and agronomic scale (AS). Environments are 1 through 3.
