An attempt was made to assess the genetic variability, heritability and genetic advance in okra [Abelmoschus esculentus (L.) Moench] using 31 diverse genotypes; were grown in randomized block design with three replications during kharif 2018 at college farm, N. M. College of Agriculture, Navsari Agricultural University, Navsari, Gujarat (India). Observations were recorded on ten characters showing considerable variability. Mean values were used to determine characters' phenotypic and genotypic variances, phenotypic and genotypic coefficients of variation, broad sense heritability and genetic advance as percentage of mean. Significant variation existed in all the characters. The phenotypic coefficient of variations was found slightly higher than the genotypic coefficient of variations for all characters studied, indicating that the apparent variation is not only genetic but also influenced by the growing environment in the expression of the traits. The moderate magnitude of PCV and GCV was observed for internodal length and number of fruits per plant. High heritability coupled with high genetic advance as per cent of mean was observed for internodal length and number of fruits per plant revealing the importance of additive gene action in the inheritance of these characters and suggested reliable okra improvement through selection of the traits.
