An experiment was undertaken on thirty eight genotypes of okra [Abelmoschus esculentus (L.) Moench] to determine the genetic variability, heritability and genetic advance in all genotypes. The wide range of variability was observed among eight characters of all genotypes. The phenotypic coefficient of variance (PCV) was generally higher than their respective genotypic coefficient of variance, thus revealing the role of environmental factors. The genotypic and phenotypic coefficient of variability were high for The genotypic and phenotypic coefficient of variability were high for edible yield per plant (91.78% and 306.85% respectively), plant height (65.12% and 177.56% respectively), number of seeds per fruit (21.07% and 33.92% respectively) and days to 50 % flowering (8.33% and 13.31% respectively) which indicates that maximum amount of variability present in the genotypes for these characters which would be amenable for further selection. High heritability (>70 %) coupled with high genetic advance (>25 %) as per cent of mean was observed for fruit diameter (71.10 % and 27.59 % respectively), indicating predominance of additive genetic component in governing of these traits and improvement of these traits through simple selection would be rewarding. It also indicates predominance additive gene action. Thus, there is immense scope for improving these characters through direct selection. Moderate heritability (>50 %) coupled with high genetic advance (>25 %) as per cent of mean was observed for number of branches per plant (52.40 % and 45.95 % respectively), number of fruit per plant (52.60 % and 27.87 respectively) and fruit length (51.20 % and 26.24 % respectively). This indicates the importance of additive effects for this trait and selection may be rewarding.
