Abstract: A study was undertaken to estimate correlation and path coefficient analysis of yieldand yield contributing traits in 50 wheat cultivars grown in Randomized Block Design with three replications during rabi season 2013-14. The grain yield per plant has significant and positive correlations both at genotypic and phenotypic levels with biological yield per plant, grain weight per main spike, 1000 grain weight and number of grains per main spike. The path coefficient analysis revealed high and positive direct effects of the number of effective tillers per plant, number of grains per main spike, 1000 grain weight, biological yield per plant and harvest index on grain yield per plant. Thus, these traits are to be considered as the most important yield contributors and due emphasis should be given while attempting yield improvement in wheat.
