Abstract:
Contemporarily the major challenge for the breeders is to select the genotypes which are high yielding across the environments. To fulfil this objective, 30 linseed genotypes were investigated at five environments with wide heterogeneity in elevation, temperature and rainfall pattern. Sixteen yield and fibre attribute were evaluated to identify the stable genotypes across the attributes. Significant differences among the genotypic, environmental and G × E interaction effects were found during the AMMI and GGE analysis. Based on results of AMMI and GGE biplots, the genotypes KL-241, KL-263 and Surbhi single lined as high seed yielding and most stable. While, the genotypes KL-284, KL-269 and KL-227 were found most stable for fibre yield per plant. The which-won-where graph of GGE biplot identified the high seed yielding genotypes viz., KL-280, KL-236 and Him Alsi-2 for specific environments (Palampur-I and Kangra). Graphs of discriminating vs representativeness were helpful to identify environments (Dhaulakuan and Kangra) having highest representativeness of the characters to discriminate the genotypes for fourteen and eleven characters out of sixteen based on their performance, respectively so that, these environments could be useful for selecting the stable genotypes during future breeding programmes.
