Studies on genetic variability, heritability and genetic advance in okra [Abelmoschus esculentus (L.) Moench]
High heritability coupled with high genetic advance observed for number of branches plant indicating that they are governed by additive gene action and could be improved through simple selection.
Abstract
Significant differences were found among genotypes for all the characters studied except number of lobes leaf, number of branches plant, number of ridges fruit, node at which first flower appear, diameter of fruit and average weight of fruit. The highest genotypic and phenotypic coefficient observed for number of branches plant. The GCV and PCV values were found influenced by environmental factors. The heritability estimates in broad sense were high for plant height and number of ridges/fruit, while low heritability estimates were observed for node at which first flower appear. The genetic advance as percentage of mean was high for number of branches plant. High heritability coupled with high genetic advance observed for number of branches plant indicating that they are governed by additive gene action and could be improved through simple selection.
