Phenotypic stability was studied in 12 fababean genotypes grown at six locations in northern plains of India. Significant genotype (G) × environment (E) interactions were observed for grain yield. Among the linear and non-linear components of G × E interaction, linear component was predominant for yield of fababean. Fababean genotypes namely, HB 115, HB 123, HB 131, HB 186 and HB 193 were found to be stable based on agronomic parameters of stability whereas genotypes HB 43, HB 123 and HB 131 were observed to be more stable when biological parameters of stability were taken into consideration. However, only two genotypes viz., HB 123 and HB 131 were found to be stable under both agronomic and biological parameters of stability. Hence, both agronomic as well as biological parameters should be applied for identification of stable genotypes in fababean.
