Genetic variability analysis for grain yield and its attributing traits among the aromatic rice (Oryza sativa L.) genotypes of Chhattisgarh region

The variability analysis showed the presence of highly significant variations for all listed genotypes tested under research experiment. Phenotypic coefficient variation traits investigation was found higher than their corresponding genotypic variation, indicating masking effect environment in expression traits. High heritability reported plant height (cm), days to 50% flowering, 1000 seed weight (g), total number spikelets per panicle, filled grain yield effective tillers plant, harvest index (%), and spikelet fertility%. degree genetic advance as a percent mean observed characters biological Plant (cm) (%). coupled with high that such controlled by additive gene action thus simple selection will be improvement this character.
