An experiment was carried out at College of Horticulture, Rajendranagar, Hyderabad summer, 2023 to study the variability, heritability and genetic advance for different morphological and agronomic traits. Analysis of variance revealed significant variability among the genotypes of okra for all character’s studied. Genetic variability revealed that a lot of variation among the genotypes. In general, the lowest difference in phenotypic and genotypic coefficients of variation indicated lowest environmental influence in controlling the expression of the traits. Based on genetic variability studies, high PCV and GCV and high heritability coupled with high genetic advance as per cent of mean were recorded for number of branches per plant at 60 DAS, number of branches per plant at 90 DAS, fruit yield per plant and yield per hectare indicating the existence of wider genetic variability for these traits in the germplasm under study.
