Genetic Analysis for Grain Yield and Its Attributing Characters in Rice (Oryza sativa L.) under Irrigated Conditions of Prayagraj, Uttar Pradesh

The present investigation was carried out to assess the genetic variability parameters, correlation and path analysis in 23 rice genotypes for 13 quantitative traits viz Days 50% flowering, Maturity, Plant height (cm), Flag Leaf Length Width Number of total tillers, Productive Tillers, Panicle Biomass (g), Harvest Index (%), Grains per Panicle, Test Weight (1000 grain weight), Grain Yield (g). Kharif 2021 season at field experimentation centre, Department Genetics Breeding, Naini Agricultural Institute, Sam Higginbottom University Agriculture Technology Sciences, Uttar Pradesh Randomized Block Design three replications. Analysis variance indicated high significant differences among all traits. Genotypes SHIATS DHAN-6, KSRV-12, DHAN-2, KSRV-140 depicted highest Plant. All characters had expressed estimates heritability. There is no evidence expressing moderate low heritability from investigation. studies on GCV PCV that presence amount variation role environment expression these yield attributing revealed plant positively significantly associated both genotypic phenotypic levels. In Phenotypic Genotypic a detailed diagonal values showed positive direct effect Yield.
