The yield stability parameters α and λ in a trial on potato varieties revealed that the highest yielder did not possess the stable yield ability and the lower yielder possessed relatively stable statistics. The new high yielding variety “E 4451” was found to be considerably stable. The locally adapted variety “Patna Red” appeared to be the most stable variety, although its yield was considerably low. Hence the variety “E 4451”, “F 5134” and K. Chandramukhi is found to be safe enough to be recommended for obtaining high as well as stable yields under Satpura plateau.
