Fig. 4. Multidimensional scaling representation of the Pearson correlation coefficients obtained from the between-groups correlation matrix (Fig. 4a), and the within-group correlation matrix (Fig. 4b), for 40 variables (trait–environment) of the groups obtained from the evaluation of 211 maize lines evaluated in eight environments (data set 2). Traits are anthesis-silking interval (A), number of rows per ear (E), yield (Y), days to silking (F), and plant height (P). Environments are 1 through 8.
