dc.description.abstractThe current study, titled “Stability analysis in barley (Hordeum vulgare L.) for yield and contributing traits under varied conditions” was conducted during Rabi 2019-20 and 2020-21 at two locations viz., Advance Centre for Rainfed Agriculture SKUAST-J, Dhiansar and Research Farm, Chatha to study the G×E interaction for stability of grain yield and component traits in barley to identify the stable genotypes and to assess the character association of yield and component traits. Analysis of variance (ANOVA) for thirteen characters of all the seventeen genotypes for individual environments i.e., E1, E2, E3, E4 has shown maximum significant results for most of the traits, which suggested the desired variability among different barley genotypes. Significant and positive correlation of grain yield per plant was observed with harvest index, number of grains per spike, plant height and flag leaf width at both genotypic and phenotypic levels. Positive and direct effect on grain yield was observed through harvest index, number of tillers per plant, plant height, SPAD values, days to 50% flowering at both genotypic and phenotypic levels in pooled environment. G x E interaction was found significant for all the characters except flag leaf width and number of tillers per plant. In stability analysis for grain yield /plant, the genotype RD-2035 was found most stable and suitable followed by RD-2849 and BH-902. These genotypes recorded high means than general mean values and with regression coefficient close to unity bi=1 and S2di=0. The genotypes RD-2035, RD-2849 and BH-902 were found stable for grain yield and other yield contributing characters namely SPAD values, flag leaf length, spike length and biological yield per plant therefore, while developing varieties for stable performance across environments such traits should be given priority. The stable genotypes can be used for future breeding programmes as well as for cultivation under varied environment for higher yield.en_US
