Potential challenge to rice is water scarcity. Water saved in rice cultivation, will help increase cultivable areas of rice and cultivation of other crops. Aerobic cultivation is one of such systems where rice is cultivated under arid conditions with minimal water. Seventy-four rice genotypes were studied under aerobic condition manifested high GCV, PCV and narrow differences in PCV and GCV for test weight, days to fifty percent flowering, plant height, grain yield per plant, plant height, panicle length, decorticated grain length& width, number of tillers, number of productive tillers, grain width. This suggested the presence of negligible influence of external factors for those traits. Present study revealed highest heritability with genetic advance as per cent means for all the traits including yield (72.28%, 57.82) except grain length & flag leaf length indicating the presence of considerable variation and additive gene effects. Hence, improvement of these characters could be effective through phenotypic selection under aerobic condition. Better performing lines from the study would be the better source for developing drought tolerant rice also saline tolerant rice under aerobic condition.
