Fig. 4

Genotype ranking in ascending order for the MGIDI index tested under E1 (A)1, E2 (B) E2, and E3 (C), with selection intensity of 15% (red circle). Selected genotypes are highlighted in red. The scale in the radar plot represents the MGIDI score. The red circle represents the threshold MGIDI score, and inner circle next to the threshold circle represents the smallest value of the scale, and the innermost circle represents the highest value of the scale. Strength and weakness view of the stable genotypes identified across three environments, shown as the proportion of each factor on the computed MGIDI index under E1 (D), E2 (E), and E3 (F). Scale represented in the strength and weakness plot depicts the contribution of factors. Immediate inner circle of the low contributing factor edge corresponds to the smallest scale value, and innermost circle corresponds to the highest scale value
