Abstract: A set of twenty six backcross inbred lines of rice (Oryza sativa L.) were assessed to study inter-relationships of phosphorus stress tolerance related traits and yield related traits under low phosphorus stress conditions. Correlation analysis revealed that grain yield per plant exhibited highly significant positive association with harvest index (0.90), spikelet fertility (0.66), number of tillers per plant (0.38), filled grains per panicle (0.29), number of panicles per plant (0.28) and leaf P (0.27).
