 ABSTRACT

Eight hedge lucerne genotypes were evaluated over four locations for analyzing stability for yield and quality. As the G x E interactions were significant for all the characters, further analysis was done for estimating the stability parameters according to Eberhart and Russell model (1966). The genotype T1 (IC 345276) was stable over all locations for the characters green fodder yield, dry matter production and crude fibre. The genotype T4 (IC 261839) and genotype T7 (TNDV 1) was stable for the character crude protein across the locations. T1 (IC 345276),       T4 (IC 261839), T6 (IC 421199) and T7 (TNDV 1) were stable over the four different locations. The genotypes T2 (IC 343710) and T8 (Thumburmuzhi local) showed stable performance under favourable environments viz., College of Agriculture, Vellayani and Regional Agricultural Research Station, Ambalavayal, Wayanad, while the genotype T5 (IC 90934) was suitable for unfavourable environment.
