(A) The strengths and weaknesses view under severe drought stress (40% FC) depicts the individual factor contributions to the MGIDI. The proximity of a factor’s contribution to the centroid signifies a closer alignment of its traits with the ideotype (ideal genotype), indicating superior performance. In contrast, greater deviations of the factor vectors from the centroid signify a suboptimal expression of the associated trait profile in the genotype. The dashed line represents the theoretical equilibrium where all factors contribute equally, serving as a reference for evaluating deviations from the ideal genetic configuration. (B) displayed genotypes that were nearly identical to the ideal genotype, based on heritability (h2), selection differential percentage (SD%), and a 15% selection pressure, using the MGIDI index. The cotton genotypes that were selected are highlighted in red, with the central red circle representing the cut-off point determined by the selection pressure.
