Genotype-environment interaction was investigated under rainfed conditions over three years (1977, 1978 and 1980) for seed yield in respect of 24 genotypes of clusterbean (Cyamopsis tetragonoloba (L.) Taub). There was a significant variation for genotypes and genotypes × environment interaction for seed yield. The genotypes HG 182, FS 277 D 39-1, 1260/17 and Durgapura safed appeared to be best suited for favourable growing season, whereas genotypes 2470/12 and 4210/16 gave stable performance under fluctuating environ mental condition. The exploitation of these genotypes in a breeding programme will help in improving the productivity of the clusterbean.
