TAILIEUCHUNG - Genetic studies of yield variation and association analysis in rice (O. sativa L.) genotype

The present investigation consists of 80 rice genotypes with seven checks and the experiment was conducted during Kharif-2017 in Randomized Block Design with two replications. The data were recorded for twelve quantitative characters to estimate the variability, heritability, genetic advance and genetic advance as percentage and association analysis. The high PCV and GCV values was obtained for grain yield per plant, effective tillers per plant, total tillers per plant, filled grains per plant, total grains per plant, flag leaf area, biological yield per plant and low PCV and GCV was observed for spikelet fertility per panicle. The traits filled grains per panicle, days to 50% flowering, test weight, plant height, flag leaf area and grain yield per plant had high heritability along with high genetic advance as per cent of mean indicate that these characters attributable to additive gene effects which are fixable and possibilities of effective selection for the improvement of these characters. The harvest index, biological yield per plant, effective tillers per plant, filled grains per panicle, total tillers per plant, total grains per panicle and spikelet fertility% showed positive and highly significant or significant association with grain yield per plant. The highest positive direct contribution on grain yield per plant at genotypic level was expressed by effective tillers per plant and spikelet fertility%, while high positive direct contribution on test weight and total grains per panicle. | Genetic studies of yield variation and association analysis in rice (O. sativa L.) genotype
