A morphometric model for variation in leaf-related traits, chlorophyll content and 100-seed weight in three soybean RIL populations. (A) and (B) Variation in leaf size is captured by PC1 with both leaf length and width having large effects, whereas PC2 describes variation in leaf shape largely through changes in leaf length and the ratio of leaf length to width. Component loading (i.e., correlations between the variables and factors) for PC1 (A) and PC2 (C) for each population are color-coded. (B) Score distribution for PC1 and PC2. Schematic representation of variation in leaf size and shape captured by PC1 (x-axis) and PC2 (y-axis), respectively (Drawn by GaphPad Prism 8.0.2)
