Multienvironment Evaluation of Tannin-Free Photoperiod-Insensitive Sorghum (Sorghum bicolor (L) Moench) for Yield and Resistance to Grain Mold in Senegal

Figure 7

Ranking genotypes for grain mold resistance based on both mean performance and stability with reference to an “ideal” genotype. The green single-arrowed horizontal line represents the AEC abscissa, and the green vertical line represents the AEC ordinate. The AEC abscissa arrowhead indicates where an “ideal” genotype should be. Its projection on the AEA was designed to be equal to the longest vector of all genotypes, and its projection on the AEC was obviously zero, meaning that it is absolutely stable. Genotypes located closer to the ideal genotype are more desirable than others. The concentric circles help to visualize the position of the genotype with respect to ideal genotype. Genotype and environment labels are represented in green and blue, respectively.
