The investigation was undertaken to generate the information on magnitude of variability, correlation and path analysis for yield and yield contributing characters of 50 aromatic rice genotypes. The results of analysis of variance indicated significant amount of variation present in this population for all traits. Medium to high values of GCV and PCV were observed for number of grains per panicle, grain yield per plant, panicle weight, plant height, test weight, head rice recovery, grain L:B ratio and alkali spreading value. High heritability coupled with high genetic advance observed in days to 50% flowering, plant height, panicle length, panicle weight, number of productive tillers per plant, number of grains per panicle, grain yield per plant, harvest index, test weight, grain L:B ratio, milling percentage, head rice recovery and alkali spreading. Grain yield per plant showed significant positive correlation with number of grains per panicle and panicle weight and negative correlation with days to 50% flowering. Panicle weight has maximum direct effect on grain yield per plant followed by number of productive tillers per plant and panicle length. Hence, these characters are identified as key traits for improving grain yield per plant.
