Twenty one advanced breeding lines selected from All India Coordinated trials and one local popular variety “annegiri’ werestudied over three years to identify high yielding stable genotypes. Genotype , environment and G x E interaction variance foundto be significant. Genotypic variance over environments was significant for grain yield , pods/plant and 100 seed weight. Bothlinear and non linear components were found to be important for the traits studied. Significant non linear component for grainyield indicated the predictability of the trait. Of all the genotypes C-506 and C-527 were found to be stable
