Correlation and path analysis was carried out at Agricultural Research Station, Tamil Nadu Agricultural University, Paramakudi to study the association between eight yield related traits during Rabi 2019-20 in 37 rice genotypes under rainfed rice ecosystem. Days to 50% flowering, number of panicles per square metre, number of filled grains per panicle and straw yield expressed positive and significant correlation with grain yield. The trait, plant height had positive and significant association with panicle length and number of filled grains per panicle suggesting that selection based on plant height is highly fruitful in developing high yielding genotypes in rainfed situation, as it will bring simultaneous improvement of these traits. The traits number of panicles per square metre, straw yield and harvest index expressed high direct effect and plant height and number of filled grains per panicle had moderate direct effect on grain yield. The traits days to 50% flowering, number of panicles per square metre and straw yield should be given more importance for enhancing grain yield under rainfed rice ecosystem.
