Abstract: The current study “The path co-efficient analysis of different component traits on yield in short grain aromatic rice (Oryza sativa L.) of Odisha†was carried out with the objective to determine the direct & indirect effects of different component traits on grain yield using path coefficient analysis to select the most promising genotypes for their subsequent future use in thirty indigenous aromatic rice cultivars. The present experiment was conducted with the materials (26 land races and 4 aromatic checks) those were evaluated in randomized block design with two replications at Rice Research station, Department of Plant Breeding & Genetics, OUAT, Bhubaneswar during kharif, 2017. The 1000-grain weight exhibited highest positive direct effect on grain yield both at genotypic and phenotypic level. Out of several characters under study, panicle numbers/plant, total grains/panicle, days to 50% flowering and days to maturity exerted highest indirect effect on yield via other traits. Single plant yield, days to maturity and 1000-grain weight had maximum contribution to genetic divergence.
