A field experiment was conducted to study the character association for 11 yield and its contributing traits in the 93 diverse indigenous genotypes of wheat (including 3 checks) at agricultural research farm Nidharia of S.M.M. Town Post Graduate College, Ballia during Rabi season 2017-2018. The experiment was laid ou tin Augmented Block Design under normal irrigated condition following standard cultural practices. The characters studied were days to 50% flowering, days to maturity, plant height, tillers per plant, spike length, flag leaf area, peduncle length, 1000-grain weight, biological yield per plant, harvest index and grain yield per plant. The grain yield per plant showed highly significant and positive correlation with tillers per plant, spike length, biological yield per plant, harvest index and test weight. While Flag leaf area and plant height showed non- significant and positive correlation with grain yield per plant. The highest positive direct effect on grain yield per plant was observed by biological yield per plant followed by harvest index, days to 50% flowering, test weight and tillers per plant while remaining traits showed negative direct effect on grain yield per plant. Hence, for the development of high yielding wheat varieties these traits possessing highly significant positive associations should be given more weightage in breeding or selection program.
