Abstract: The present investigation entitled “Study of Path Coefficient Analysis of some Quantitative Traits in Wheat (Triticum aestivum L.)” was undertaken to study the path coefficient analysis for grain yield and its components. A set of twenty genotypes of Wheat were evaluated over two years from 2015-16 to 2016-17 to assess the genetic analysis of these genotypes for yield and its contributing traits over years and environments. Experiment was conducted in randomized complete block with 3 replications and two dates of sowing i.e. 3rd week of November (timely sown) and 1st week of January (very late sown). In the study number of tillers plant-1 showed highest positive direct effect on grain yield plant-1, followed by biological yield plant-1, harvest index, number of grains plant-1, ear weight and number of spikelets ear-1. It means direct selection of these traits may reward. However, days to maturity, plant height, days to 50% flowering, ear head length, peduncle length, 100 grain weight, number of ears plant-1, number of grains ears-1, number of dead tillers plant-1 and number of effective tillers plant-1 recorded negative direct effect on grain yield plant-1. Greater part of indirect effects was recorded via other traits were only such traits viz., biological yield plant-1, number of tillers plant-1, number of effective tillers plant-1/number of ears plant-1, harvest Index, number of grains plant-1, ear weight and number of spikelets ear-1 having high to moderate positive indirect effects. This indicated that these were main contributors to the grain yield.
