“…Genetic advance as a percent of mean was found to be high for grain yield per plant (99%), biomass per plant (89.89%), harvest index (85.57%), number of filled grains per panicle (80.74%), number of tillers per plant and effective tillers per plant (63.34% and 61.48%), test weight (39.23%), days to 50% flowering (35.36%), plant height (27.22%) and spikelet fertility (20.13%) and medium for panicle length (12.5%). These findings were in agreement with Bansidhar et al [18] for panicle length and Ratnam et al [19] for days to 50% flowering, plant height, effective tillers per plant, number of filled grains per panicle and test weight.…”

“…In plant breeding programs genetic variability augmented with heritability is important for selection of superior genotypes. Heritability is the portion of phenotype variability that can be attributed to genetic variation [18]. High broad sense heritability was found in test weight (96.47%), plant height (95.81%), days to 50% flowering (93.93%), grain yield per plant (92.47%), filled grains per panicle (86.51%), biomass per plant (80.6%), panicle length (74.99%), spikelet fertility (70.75%), total number of tillers per plant (62.68%), total number of effective tillers per plant (60.67%).…”

Submergence is the third most important abiotic stress hugely affecting yield and productivity in rice. There are many wild varieties and landraces available which are tolerant to submergence stress. These genotypes can be utilized as donors in different breeding programs. The population derived from such germplasms are subjected to genetic evaluation for yield and yield related attributes for development of lines that are high yielding as well as tolerant to submergence. The present investigation was executed in 120 Recombinant Inbred Lines (RIL) population (F10) derived from Swarna-Sub1 x AC 20431B along with four land races and Swarna-Sub1 to elucidate the association existing between yield and yield attributing characters. Apart from this, Correlation and path analysis was also employed to study direct and indirect effect on grain yield. Observations for agro-morphological traits such as days to 50% flowering, plant height, panicle length, total number of tillers, number of effective tillers per plant, number of filled grains and Spikelet fertility, test weight, grain yield per plant, biomass per plant and harvest index were recorded and analyzed for various variability parameters. Correlation and path coefficient analysis were also carried out. High heritability and genetic advance values were observed for days to 50% flowering, plant height, panicle length, total number of tillers per plant, effective tillers per plant, filled grains per panicle, spikelet fertility, test weight, grain yield and biomass per plant. Among all the characters; filled grains per panicle, biomass and harvest index per plant showed significant correlation with grain yield. Effective number of tillers per plant has the highest positive direct effect on grain yield.
