Figure 1
Ranking of genotypes based on the Multi-Trait Genotype-Ideotype Distance Index (MGIDI) for Frederico Westphalen/RS (A) and Pato Branco/PR (B). The red line refers to the selection intensity of 25%, accounting for the selection of 2 genotypes.

Figure 2
Visualization of the strengths and weaknesses of all genotypes studied for the Frederico Westphalen/RS (A) and Pato Branco/PR (B) environments. The dashed line indicates a theoretical value where all factors would contribute equally.
