Abstract:

An experiment was conducted during kharif 2017 comprised of 25 genotypes of aromatic and pigmented rice to study character interrelationship using correlation and path analysis. Correlation coefficient revealed that leaf length of blade, stem length, time of 50% heading, number of filled spikelet per panicle, 1000 grain weight, spikelet fertility %, biological yield per plant, harvest index per plant and days to maturity showed positive significant correlation with grain yield per plant at genotypic level. And stem length, number of filled spikelet per plant, 1000 grain weight, spikelet fertility %, biological yield per plant and harvest index per plant showed positive significant correlation with grain yield per plant at phenotypic level. Path analysis revealed that leaf width of blade, time of 50% heading, number of panicle per plant, number of filled spikelet per panicle, 1000 grain weight, grain width, grain length and grain width ratio, biological yield per plant and days to maturity had positive direct effect on grain yield per plant.
