Soybean Root System Architecture Trait Study through Genotypic, Phenotypic, and Shape-Based Clusters

Figure 1

Pearson’s correlations of root traits. Correlations at 9 days after germination measured on 292 soybean genotypes (). Hierarchical clustering was used to group similar traits. Symbols (shape and color) denote RSA traits used in the corresponding iRoot index (cumulative trait scores).
