The experiment was laid out in Randomized complete block design with three replications. Analysis of variance revealed significant differences among the genotypes for all studied traits except tillers m-². Heritability estimates were lowest for tillers m-² while, highest for days to heading. High heritability was observed for days to heading while moderate heritability was observed for flag leaf area, plant height, spike length, 100-grain weight, biological yield and harvest index. The highest grain yield was produced by G-34, G-11 and G-9 followed by G-5, G-11, G2, G-27, G-33,G-4,G-35, and G-36. Tillers m-2, flag leaf area, plant height, spike length and biological yield showed positive and significant association with grain yield. These results suggest that all the traits showing significant correlation with grain yield which needs better attention in future wheat breeding programs for increasing yield.
