Shoot architecture traits show high correlation to both canopy coverage as well as light interception in soybean. Best linear unbiased predictions (BLUPs) were calculated from all 2018 and 2019 data and used for correlation analysis. Pearson correlation (FDR adjusted p value < 0.05) between different traits is shown as a heat map. Traits in the heat map are: Branch angle (BA), Branch density/ distribution (BD), Branch number (BN), Branch orientation (BO), Branching zone (BZ), Branch ratio (BR), Days to 50% canopy coverage (CC50), Canopy coverage at R2 (CCR2), max growth rate (%/week) (MCC_w), Average Canopy Coverage (ACC), Canopy Height (CH), Height at 50% tPAR (H50PAR), tPAR at 50% height (PAR50H), tPAR at ground level (PARG), Internode length at node 4 from the top of the plant (IL4), Slope of the top four internodes (IS4), Leaf area (LA), Leaf Length (LL), Leaf Width (LW), Number of nodes (NO), Petiole angle at node 4 from the top of the plant (PA4), Petiole length at node 4 from the top of the plant (PL4), Slope of the top four petioles (PS4), Plant Height (PH), Plant shape parameter peak height (Sh_H), Plant shape parameter area under the curve (Sh_A), and Plant shape parameter width scaling factor (Sh_W)
