%X A field experiment was conducted during wet season 2009 to study the response of rice genotypes under aerobic conditions.Variance studies revealed significant differences among the genotypes for the traits, days to flowering, plant height, harvestindex, grain yield, panicle number, straw yield, panicle length, test weight and biomass. Higher values of heritability and geneticadvance were observed for plant height and days to flowering. Grain yield per plot showed positive association with harvestindex and total biomass. Correlation and path analysis revealed an ideal plant type of genotype under aerobic conditions shouldhave high harvest index and biomass. Eight rice genotypes with increased yield advantage over checks have been identified assuitable entries for aerobic cultivation. Results also suggested that all rice genotypes are not suitable for aerobic method ofcultivation and the genotypes which are able to acclimatize to the non-puddled aerobic conditions should be identified andreleased.
