Résumé
Tiger nut (Cyperus esculentus L.) is a cash crop that is very rich in nutrients. Knowledge of the agronomic performance of genotypes cultivated for broad adaptation in growing environments is necessary. The objective of this study was to identify high-performance genotypes in Burkina Faso. Thus, 42 genotypes were evaluated using an Alpha Lattice design of 21 genotypes × 2 blocks in four replicates during the 2021-2022 growing season. The combined analysis of variance showed significant effects of genotype, environment, and genotype x environment interaction for most of the measured variables. The representation of the effect of genotypes and the genotype x environment interaction revealed high-performing and specific genotypes in each environment. For the number of leafy shoots, genotypes K35J and B45J have performed well in environment 2 (E2) and N1MC have performed well in environment 1 (E1). For tuber yield, B44MC and K25MC performed best in E2 and K35J and K28J in E1. These genotypes could be promoted for the production of tiger nut in the Sudanese and Sudano-Sahelian zones of Burkina Faso, taking into account the needs of producers and consumers.
