Stability for protein, lysine, tryptophan and total sugar content was examined in 40 diverse genotypes of sorghum [Sorghum bicolor (L.) Moench] in six environments. Both linear and non-linear components of genotype X environment interaction were significant for protein while non-linear components were significant for others. In general, hybrids were more stable than varieties and advanced breeding lines. Varieties CSH 9, D 71196, CSH 5 and SPV 225 were stable for most characters and hence can be used in breeding for nutritionally superior cultivars.
