The performance of most crop genotypes is strongly influenced by genotype-environment interactions. Thus, finding good-performing and adapted nutsedge genotypes is necessary for growers to improve their productivity. Consequently, the aim of this study is to understand the effect of genotype x environment interaction (GEI) on tuber yield and to select high-yielding genotypes specifically or broadly adapted to production. 36 genotypes were evaluated in three environments, following an alpha lattice design of 18 genotypes × 2 blocks in four replications. The combined AMMI analysis of variance indicated that the main effects due to environments, genotypes and genotype x environment interaction were significant. The contribution of environment (E), genotype (G) and genotype × environment interaction (G×E) to the total variation in tuber yield was 36.81%, 10.80% and 6.77% respectively. The genotypes × environments interaction was represented using the GGE-biplot method. The PCA1 and PCA2 axes accounted for 47.67% and 39.49% respectively of the total variability due to the G + G×E effect. Genotypes B32 (2.21Tonnes ha-1), P123 (1.71Tonnes ha-1) performed best specifically in environment 1, genotypes C65 (4.69Tonnes ha-1), B43 (4.21Tonnes ha-1) in environment 2 and genotypes K25 (3.17Tonnes ha-1), M5 (3.10Tonnes ha-1) in environment 3. Genotype C69 was the ideal genotype and genotypes P181, B44, C65 and B43 were the desirable genotypes for tuber yield in all three environments. The high-performance genotypes C65, B43 could be popularized for nutsedge production in the Soudano-Sahelian zone and the high-performance genotypes K25, C69 for the Soudanian zone in Burkina Faso.

Abstract
The performance of most crop genotypes is strongly influenced by genotype-environment interactions. Thus, finding good-performing and adapted nutsedge genotypes is necessary for growers to improve their productivity. Consequently, the aim of this study is to understand the effect of genotype x environment interaction (GEI) on tuber yield and to select high-yielding genotypes specifically or broadly adapted to production. 36 genotypes were evaluated in three environments, following an alpha lattice design of 18 genotypes × 2 blocks in four replications. The combined AMMI analysis of variance indicated that the main effects due to environments, genotypes and genotype x environment interaction were significant. The contribution of environment (E), genotype (G) and genotype × environment interaction (G×E) to the total variation in tuber yield was 36.81%, 10.80% and 6.77% respectively. The genotypes × environments interaction was represented using the GGE-biplot method. The PCA1 and PCA2 axes accounted for 47.67% and 39.49% respectively of the total variability due to the G + G×E effect. Genotypes B32 (2.21Tonnes ha-1), P123 (1.71Tonnes ha-1) performed best specifically in environment 1, genotypes C65 (4.69Tonnes ha-1), B43 (4.21Tonnes ha-1) in environment 2 and genotypes K25 (3.17Tonnes ha-1), M5 (3.10Tonnes ha-1) in environment 3. Genotype C69 was the ideal genotype and genotypes P181, B44, C65 and B43 were the desirable genotypes for tuber yield in all three environments. The high-performance genotypes C65, B43 could be popularized for nutsedge production in the Soudano-Sahelian zone and the high-performance genotypes K25, C69 for the Soudanian zone in Burkina Faso.
