Assessment of Genetic Variability for Yield & Its Contributing Traits in Rice (Oryza sativa L.)

The research work was executed Research cum Instructional Farm, Genetics and Plant Breeding department of IGKV Raipur (C.G.) during kharif 2021. material under comprised 50 rice germplasm lines including two checks namely Mahamaya Rajeshwari, which were tested in RBD with replications. observation investigation recorded for total eight characters viz. Days to 50% flowering, Number tillers per plant, Panicle length(cm), height(cm), 1000seed weight(g), Grain yield plant(g), Biological Harvest index(%). analysis variance showed that there a highly significant variation genotypes all the studied characters. A small difference between PCV GCV suggests environment has little impact on concerning traits. number 1000 seed weight, grain biological plant harvest index had high heritability along genetic advance as percent mean indicates is most likely caused by additive gene action selection may be effective.
