The present study, fifty exotic and indigenous lines of barley, showing wide spectrum of variation for various characters, were evaluated in irrigated conditions during Rabi, 2019-20. The experiment was conducted in Augmented Block Design having 5 blocks and checks were repeated after twenty-five germplasm each, at Genetics and Plant Breeding Research Farm, Acharya Narendra Deva University of Agriculture and Technology, Narendra Nagar (Kumarganj), Ayodhya. The characters studied were days to 50 % flowering, days to maturity, plant height, productive tillers per plant, flag leaf area, spike length, 1000-grain weight, biological yield per plant, harvest-index and grain yield per plant. The data recorded on these characters was utilized for estimation of mean, range, correlation, path-coefficient analysis and genetic divergence. A wide range of variation for different characters and comparison of means of germplasm lines using least significant differences, indicated existence of very high degree of variability for all the characters in the germplasm collection. The variation due to treatment all varieties were found highly significant at 1% probability level for all the characters and no any character was found non-significant.The most promising lines showing highest seed yield with high mean performance for other yield contributing characters were identified as ISB-20262, ISB-20318, ISB-20202, ISB-20249 and ISB-20218.EnglishThesis
