A 4-year rainfed experiment showed a significant variation for genotypes and genotype x environment interaction for seed yield of 14 genotypes of sesamum (Sesamum indicum Linn.). The linear as well as non-linear components were significant. Deviation from regression was significant for most of the genotypes for seed yield. 'TC 25' gave the maximum mean grain yield (257.50 kg/ha) and showed near-unit responses under fluctuating environments. 'T 13', 'T 43', '4-2' and 'Pratap' were better genotypes in favourable growing seasons (with better rainfall distribution). 'N 32' performed better especially in the years of long spell of drought. An improvement in stability of these genotypes through breeding programmes would lead to the improvement of the productivity of the crop in the region
