The experiment was conducted at Crop Research Form, Nawabganj Department of Genetics and Plant Breeding, CSA, University of Agriculture and Technology, Kanpur, U.P, India. The experiment was carried out 10 divers genotypes grown in Randomized Block Design with three replications followed by diallel mating design. Observations were recorded on five randomly selected plants for all 15 characters from each replication. The estimates of heritability revealed high value for plant height, number of productive tillers per plant, seed hardness and protein content; moderate heritability for spike length, number of spikelets per spike, 1000-grain weight, biological yield per plant and grain yield per plant; low heritability was observed for number of grains per spike in both F1 and F2 generation. While high genetic advance in percentage over mean were estimated for number of productive tillers plant, flag leaf area, number of grains per spike, biological yield per plant, grain yield per plant, phenol color and seed hardness; Moderate values were observed for spike length, 1000 grain weight, harvest index and protein content; Low values of genetic advance were recorded for days to 50% flowering, days to maturity and number of spikelets per spike in both the generation.
