Stability analysis of variance in grain amaranth showed significant differences among the genotypes for days to 50% flowering, plant height and number of spikelets/panicle indicating the presence of variability among the genotypes. Significant linear component against pooled deviation for days to 50% flowering, plant height and yield/plant indicated that the major component for differences in stability was due to linear regression and the performance can be predicted with some reliance under different environments. Among the 20 genotypes tested for stability of performance, no single genotype possessed ideal characteristics of a stable genotype for all the traits over the eight environment tested. However, regarding the grain yield/plant, IIHR-11, IIHR-22 and IIHR-46 were found to be responsive (b<1.0) over the environments, hence more adaptable to normal growing conditions.
