Abstract
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.  
Highlights
Groundnuts are main food product for thousands of small scale farmers in Mali
FAOSTAT (2015) data on groundnut production showed that, for the country, the increase in groundnut production resulted from the expansion of the area cultivated and increase in the number of farmers involved in the production rather than the increase of yield productivity per se for more than 50 years
The groundnut production is rain-fed in Mali and most of the time; the growing phase terminates under a period of drought
Summary
Groundnuts are main food product for thousands of small scale farmers in Mali. Other studies indicated that severe drought occurred twenty times during 55 years in Mali (Ndjeunga et al, 2003). SAS Institute 2009 argued that in West Africa, groundnut productivity follows similar trends with the rainfall pattern, which is mostly dominated by the occurrence of recurrent drought spells. The groundnut production is rain-fed in Mali and most of the time; the growing phase terminates under a period of drought. This exposes the crop to end-of season drought causing
