The present investigation entitled “Estimates of Direct & Indirect Effects along with Correlation Coefficient analysis in Bread Wheat (Triticum aestivum L.)” involving forty four genotypes was aim to study the correlation coefficient, path coefficient. All the forty four wheat genotypes were tested in randomized block design with three replications during rabi 2016-17 at Crop Research Centre, Chirori, SardarVallabhbhai Patel University of Agriculture and Technology, Meerut, (U.P.). The traits under study were days to 50% flowering, days to maturity, plant height, number of productive tillers per plant, spike length, total number of spikelets per spike, number of grains per spike, biological yield per plant, grain yield per plant, harvest index, 1000 seed weight and protein content. Correlation analysis indicated that in grain yield per plant was highly significant and positivity correlated with biological yield per plant and productive tillers per plant and significant and positivity correlated with harvest index. Genotypes from the same geographical region fell into different clusters and vice-versa. In the present investigation, grain yield was positively and directly affected by biological yield per plant, harvest index, total number of spikelets per spike, days to maturity, protein content and plant height, This suggested that selection of parents for hybridization should be on genetic diversity rather than on the geographical areas.
