The research work was executed Research cum Instructional Farm, Genetics and Plant Breeding department of IGKV Raipur (C.G.) during kharif 2022. The research material under research comprised of 28 rice germplasm lines including four checks namely Swarna, MTU 1318, Pooja and, Jaldubi which were tested in RCBD with two replications. The observation of research investigation were recorded for total twenty characters.

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 characters for which highest and lowest heritability obtained were grain yield per plant (95.92) and days to maturity (41.58), respectively and medium estimates of heritability obtained for 1000 seed weight (g) (51.68%). For quality trait, grain elongation ratio medium heritability estimates were obtained and all other quality characters showed high estimates of heritability which were head rice recovery (%) (99.37%). The advance breeding lines showed genetic advance as% of mean from low to high value. While, noting for genetic advance as percent of mean, the yield characters observed with highest value was number of effective tillers per plant (48.99%) and least value was obtained for traits, days to maturity (5.87%) along with high genetic advance as a percent of mean indicates that the heritability is most likely caused by additive gene action and selection in batter generations may be effective.
