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

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
