Principal Component Analysis for key traits for the wheat dual-purpose ideotype. A Principal Component Analysis (PCA) was performed based on GY, SY, lodging susceptibility, and biogas production kinetic parameters for the 36 wheat genotypes (see Table 1 for numeric reference). Correlation of traits with PC1 were 0.913, 0.868, 0.415, − 0.415 and 0.06 for GY, SY, Bmax, ∆LS, and k, respectively. Correlation of traits with PC2 were 0.843, − 0.599, − 0.504, − 0.080 and − 0.018 for k, ∆LS, Bmax, GY, and SY, respectively. Ellipse was empirically built
