Fig 1.
Additive main effects and multiplicative interaction (AMMI1) biplot based on Principal Component 1 (PC1), illustrating G × E interactions of quinoa genotypes.
G1, G2, G3, G4, and G5 represent the Q1, Cahuil, G18, Isluga, and Q3 genotypes. E1, E2, E3, and E4 represent four environmental treatments, namely control, waterlogging, salinity, and drought stress, respectively.
Fig 2.
Additive main effects and multiplicative interaction 2 (AMMI2) biplots based on PC1 and PC2 illustrating G × E interactions of quinoa genotypes.
G1, G2, G3, G4, and G5 represent the Q1, Cahuil, G18, Isluga, and Q3 genotypes. E1, E2, E3, and E4 represent four environmental treatments, namely control, waterlogging, salinity, and drought stress, respectively.

Genotype plus genotype by environment interactions (GGE) plot for genotype comparison with the ideal genotype plotted near the center of the concentric circles.
G1, G2, G3, G4, and G5 represent the Q1, Cahuil, G18, Isluga, and Q3 genotypes. E1, E2, E3, and E4 represent four environmental treatments, namely control, waterlogging, salinity, and drought stress, respectively.
