The Study of Genetic Components in Okra [(Abelmoschus esculentus L.) Moench] Crop

Abstract

The present study of the genetic component in okra [Abelmoschus esculentus (L.) Moench]” crop was conducted during Kharif 2019 to ziad 2020 at the research farm of shri Durgaji post-graduate college Chaneshwar Azamgarh U.P. with ten genotypes Azad Bhindi1, Azad Bhindi 2, Azad Bhindi 3, KS 312, VRO5, KS 442, KS 439, BO2, Arka Abhay and Prabhani Kranti along with 11 characters viz days to flowering, height of plant, number of branches per plant /main shoot, number of first fruiting node height of first fruiting node number of nodes per plant, length of internodes, length of fruit, width of fruits, number of fruits per plant and fruit yield per plant.  The genetic component of variance showed significant values for additive components for all the characters in both the generations except the height of the plant and the number of branches in F1 generation. The dominance components  were also highly significant for all the characters in both generations except fruit yield per plant in F2 population. The degree of dominance  showed dominance for all the characters in both generations. The ratio  showed less than unity for all the characters in both generations. Analysis of variance for combining ability showed highly significant values both for gca and sca variances based on both generations. However, the magnitude of the GCA variance was more than the sca variance for all the characters in both F1 and F2 generations. Additive gene action was observed for all the characters in both generations.
