A critical analysis of both character association and path analysis indicated that among several yield components in rice, number of filled grains per panicle are playing key role for better yields under aerobic situation. The studies indicated that grain yield is primarily contributed by filled grains per panicle and 1000 seed weight. As a highly significant correlation was noticed between panicle length and plant height and also between panicle length and grains per panicle, stature of plant is very important under aerobic condition. Hence medium stature plant with long panicle, sturdy culms and more grains per panicle would be highly advantageous for this situation. Other important traits for simultaneous consideration for yield enhancement are spikelet fertility and 1000 seed weight.

Keywords: Correlation, Path analysis and aerobic rice.
