ABSTRACT: The study compared 37 new soybean genotypes and three local controls in two agroecological zones in Burkina Faso using an alpha-lattice design. Analysis of variance (ANOVA), additive main effects and multiplicative interaction (AMMI) analysis, and genotype plus genotype-environment interaction (GGE) biplot analysis revealed highly significant effects of genotype, environment, and genotype-environment interaction, as well as high stability and high yield for five genotypes (TGX2017-6E, TGX1987-14F, TGX1987-10F, TGX2018-5E, and TGX2007-3F). Three lines showed specific adaptation to the wetter southern Sudanian site, and no severe symptoms of rust or mosaic virus were reported. Variety registration could be considered for the most stable genotypes, with Fada N’Gourma as the main trial site.
