The study was conducted during winter season of 2022 at National Wheat Research Program of the National Agriculture Research Council at Omsatiya, Rupandehi with the objective to identifying appropriate seeding rate for promising wheat genotypes. The experimental design was split pot with three replications. The main plot comprised of three seeding rates (90,120 and 150 kg/ha) and sub plot consisted of six promising wheat genotypes (NL1330, NL1345, NL1425, NL1450, BL1488, Bandganga (control)). Results revealed that among the tested genotypes, NL 1450 produced the highest grain yield of 4471kg/ha at seeding rate of 150kg/ha which was statistically at par with 120 kg/ha followed by BL1488 at seeding rate of 120 kg/ha. That genotype NL 1450 also had the maximum number of kernels per spike as compared to other genotypes. The genotypes X seeding rate interaction effect on all the yield attributing characters was found statistically non-significant. However, genotype NL1450 being the highest grain yielder should be tested further for confirming its superiority for release.
