Abstract: A research was carried out to measure genetic variability and correlation among selected traits in wheat with the use of fourty-three genotypes available at Department of Genetics and Plant breeding, Sam Higginbottom University of Agriculture Science and Technology, Allahabad during Rabi, 2015-16 under irrigated condition in augmented block design-2. Analysis of variance revealed significant differences for 14 characters studied among the genotypes and checks vs genotypes. High phenotypic and genotypic coefficients of variation were obtained in seed yield/plant, biological yield and harvest index. High heritability accompanied with high expected genetic advance was reported from flag leaf length, plant height, no. of grains/spike, test weight, biological yield, harvest index and seed yield/plant. Both at phenotypic and genotypic level, traits like grain filling period, no. of tillers/plant, test weight, biological yield and harvest index exhibited strong association with seed yield/plant at desirable direction. Thus, traits showing variability and desirable correlation both at genotypic and phenotypic levels and high heritability coupled with high genetic advance envisage the use of these traits for improvement of grain yield of wheat.
