Abstract: The present investigation entitled “Study of correlation and path coefficient analysis in bread wheat (Triticum aestivum L.)” was carried out during rabi 2016-2017 at Crop Research Farm, Nawabganj of Chandra Shekhar Azad University of Agriculture and Technology, Kanpur (U.P.). A collection of fifty wheat genotypes from different eco-geographic origins were evaluated for nine quantitative characters. Data were recorded and analyzed on the bases of following 11 characters viz, days to flowering, days to maturity, plant height, number of productive tillers per plant, length of spike, number of grains/spike, grain weight/spike, 1000-grain weight, and grain yield per plant. Generally, the estimates of genotypic correlation coefficients were higher than the corresponding phenotypic correlation coefficients for all the character combinations. Grain yield per plant shows positive and significant associationship with days to flowering, days to maturity, spike length and number of productive tiller per plant. Path coefficient analysis indicated that the highest positive direct effect on seed yield per plant was exerted by spike length, days to maturity, number of productiver tillers per plant, 1000-grain weight, grain weight per spike.
