Supplementary figures. A collection of extra figures which may be of interest to readers but that arenâ t in the main scope of the submission. Figures S1â S4 show step-wise discriminant analyses plots using different subsets of the traits measured (root morphology traits, leaf mineral composition traits, seed mineral composition traits, & seed yield traits respectively). Plots from analyses using the full set of traits are included as a main figure in the submission; see Fig. 7. Figures S5 and S6 are box and whisker plots of seed yield data by crop habit and thousand seed weight by genotype release date respectively. (PPTX 429 kb)
