Abstract:
In the present investigation, 90 indigenous lines of wheat along with 4 checks were evaluated in timely sown, irrigated and reclaimed salt affected soil during Rabi, 2015-16. The trial was conducted in augmented block design at the main experiment station of Narendra Deva University of Agriculture and Technology, Kumarganj, Ayodhya. The characters studied were days to 50% flowering, flag leaf area (cm²), spike length (cm), plant height (cm), tillers per plant (cm), peduncle length (cm), days to maturity (cm), 1000-grain weight (g), biological yield per plant (g), grain yield per plant (g) and harvest index (%). The data on 11 quantitative traits was utilized for estimation of correlation and path coefficients among traits. A very strong positive association of grain yield per plant was observed with biological yield per plant followed by harvest index, test weight, days to 50% flowering and days to maturity. The path analysis identified biological yield per plant followed by harvest index as the major direct positive contributors towards expression of grain yield per plant while harvest index, tillers per plant, peduncle length and plant height are emerged as most important indirect yield components. The characters showing highly significant positive correlation among yield and its components suggest that during selection these may be given due to importance for developing high yielding varieties.
