Abstract:
The present investigation was carried out on seventy six genotype of bread wheat including six checks with in objective to study the correlation of different quantitative traits with grain yield per plant and among themselves, direct and indirect effects of various yield components for select of superior genotypes. The experiment was carried out during the Rabi season at the research farm of RPCAU, Pusa. The observations were recorded on Germination %, Early vigour, Root: Shoot ratio, Relative leaf water content, Plant height, Flag leaf area, Specific leaf weight, Number of productive tillers per plant, Spikelet sterility, Number of grains per spike, 1000- grain weight, Grain yield per plant, Biological yield per plant, Harvest-index. The mean data with respect to these traits were subjected to statistical analysis. Correlation studies exhibited positive and highly significant correlation for almost all the traits studied with grain yield per plant except spikelet sterility and plant height, Biological yield per plant, harvest index, flag leaf area and root: shoot ratio showed maximum positive direct effects on grain yield per plant. Most of the quantitative traits showed maximum indirect effect through biological yield per plant.
