Rice as a cereal grain is the most widely consumed staple food for a large part of world’s human population, especially in Asia. Estimation correlation among different characters was undertaken by taking into consideration 8 CMS line and their maintainer lines. At genotypic level, grain yield per plant showed highly significant and positive correlation with date of panicle initiation, 50% panicle emergence, 100% panicle emergence, panicle per plant, no. of tillers and days of maturity and negatively correlated with pollen sterility. Path coefficient analysis revealed at phenotypic level number of tillers had highest positive direct effect towards grain yield per plant followed by days to maturity, 50% panicle emergence, main stem length, 100% panicle emergence, spikelet per plant, test weight, panicle length and stigma length. | Correlation of characters and path analysis among different traits of CMS lines and maintainers
