Abstract

Forty genotypes of potato were grown in twelve environments and analysed for stability of tuber yield per plant. Thirty two genotypes were responsive towards environmental variations. Twenty three genotypes were found to be stable. Fourteen of these twenty three genotypes (Kofri Chandrmukhi, Kufri Alankar, Kufri Chamatkar, Kufri Sheatman, Kufri Lauvkar, Kufri Muthn, Kufri Dewa, Kufri Safed, Craigs Defiance, Fabricia, Goya, JF-246, JF-303 and Saco) had high mean performance. Four other genotypes were suitable for rich environmental conditions, since they had high men and their regression coefficients exceeded unity.
