Genotype x environment interactions for green fodder and dry matter yield in clusterbean (Cyamopsis tetragonoloba (L.) Taub.) were studied by growing 14 genotypes over four years. The genotypes showed significant interactions with the environment for both the traits and a large portion of these interactions was accounted for by the linear regression on the environmental index for dry matter yield, whereas the reverse was the case for green fodder yield. The genotypes, HFG 156 and HFG 119 were most stable with high yield and unit regression coefficient for both the traits studied.
