Treatment ranking based on the MGIDI (a), the strengths and weaknesses view of the treatments (b), and the biplot of the principal component analysis performed with the studied traits for the cultivar × origin interaction (c). Strengths and weaknesses are shown as the proportion of each factor on the computed multi-trait genotype-ideotype distance index. The smallest the proportion explained by a factor (closer to the external edge), the closer the traits within that factor are to the “ideal” treatment. The selected factor combinations were used to compute the selection differentials
