Twelve varieties/hybrids of potato were evaluated for stability of tuber yield over five years. Significant differences were observed among varieties/hybrids, years and varieties × year components of variation. Both linear and non-linear components of variations were significant, with the preponderance of linear component. Hybrid MS/82-638 was high yielding and responsive to good environmental conditions. Hybrids PS/M-75 and JI-5857 gave 14.0 and 11.0 per cent significantly higher yield than the best released variety ‘Kufri Badshah’. Hybrid JH-222 was identified to begood genotype for poor environmental conditions.
