Sixteen groundnut genotypes were evaluated under three different environmental conditions of Mali during 2015/2016 rainy season. The environments were Tioribougou, Djijan and Samanko affiliated at International Crops Research Institute for the Semi-Arid Tropics (ICRISAT). The experiments were conducted in a 2×8 alpha lattice with three replications. Within the environment, the main effect of a genotype was significant. Genotypes by environmental interaction were also significant. Results showed that three genotypes ICGX-IS 13005F2-B1-287-1 (grain yield 2,197.1 kg/ha), ICGX-IS 13005F2-B1-205-1 (grain yield 1,922.3 kg/ha) and ICGX-IS 13012F2-B1-29-1 (grain yield 2,106.0 kg/ha) were found to be stable across environments. The genotypes with high pod yield for each specific environment were ICGX-IS 13005F2-B1-287-1 with 2197.1 kg/ha in Tioribougou and ICGX-IS 13005F2-B1-252-1 with 2382.8 kg/ha in Samanko. Key words: Groundnut, yield, genotype × environment interaction.
