Online Published on 4 September, 2024. Abstract The present investigations were carried out on fifty three rice genotypes to select the better lines for yield traits in randomized block design with three replications during kharif 2023. The variance studies showed significant variations among all the genotypes, suggesting significant genetic variation in the material. The phenotypic coefficient of variation (PCV) was higher than genotypic coefficient of variation (GCV) for all the traits. The yield traits which showed high values for genetic advance as per cent of mean along with high heritability were number of unfilled grains per panicle followed by number of filled grains per panicle, number of total grains per panicle, grain yield per plant, number of panicles per plant, number of total tillers per plant, harvest index, test weight, plant height, biological yield per plant and panicle length, revealing the prevalence of additive gene action, thus providing scope for further improvement through selection.
