A comparison of different stability models for genotype x environment interaction in pearl millet

Abstract

Twenty four genotypes (hybrids) of pearl millet were tested under eight environments in Gujarat. The models of Eberhart and Russell (1966), Perkins and Jinks (1968) and Freeman and Perkins (1971) applied to study genotype x environment interaction and were compared for their efficiency empirically. The genotypes GHB-788, GHB-832 and GHB-840 were observed as most stable and widely adapted over environments in all three models. On the basis of simplicity and computational convenience, Eberhart and Russell (1966) model was recommended.
