The present investigation was carried out to study the correlation and path analysis in one hundred and thirty four germplasm of rice (Oryza sativa L.). Character association of the yield attributing traits revealed significant positive association of grain yield per plant with panicle length, number of effective tillers per plant, panicle weight, number of filled grains per panicle, total number of grains per panicle and test weight. Hence, selection for these traits can improve yield. The number of effective tillers per plant, filled grains per panicle, test weight, panicle weight, total number of grains per panicle, days to maturity, panicle length and kernel breadth exhibited positive direct effect on yield. Among these characters, number of effective tillers per plant possessed both positive association and high direct effects. Hence, selection for this character could bring improvement in yield and yield components.
