 ABSTRACT

Aerobic cultivation system of rice is important to meet the growing food demand as irrigated cultivation system faces limitation due to scarcity of water resources. Considering it, present investigation was carried out to identify potential genotypes which can suite aerobic condition. Ten genotypes were evaluated in a randomised blocked design with five replications. All genotypes exhibited significant variation for all the traits. The phenotypic coefficient of variation was slightly greater than genotypic coefficient of variation indicating a negligible influence of environment over these traits. All the characters recorded high heritability ranging from 61.89 to 96.19 percent. Heritability in conjugation with high genetic advance per mean for all the traits were recorded indicating that these traits could be use in future hybridization programme.

Key words: Aerobic rice, Genotypic Coefficient of Variation, Heritability, Genetic Advance as   percent of Mean.
