The experiment was undertaken to estimate the genetic variability, correlation and path coefficient analysis of yield and its attributes in thirty eight wheat genotypes grown at research farm of P.G. College Ghazipur during Rabi season 2020-21. Wide genetic variation was observed among genotypes for all the characters studied considering the genetic parameters. The magnitude of phenotypic coefficients of variation (PCV) were higher than the corresponding genotypic coefficient of variation (GCV) for all the characters under investigation, indicating the influence of environmental factors on other experiment. High heritability with high genetic advance as percent of mean was observed for plant height, seed yield per plant, 100 grain weight, days to 50% flowering, biological yield, number of grain per spike and spike length. The grain yield per plant had significant and positive correlation with biological yield, spike length, and plant height. The magnitude of direct and indirect effects revealed that 100 grain weight was the most important traits followed by spike length, days to maturity and harvest index for improvement of grain yield in wheat.
