Evaluation of Genetic Variation, Heritability and Genetic Advance for Various Traits in Okra [Abelmoschus esculentus (L.) Moench] under north Gangetic Plains of Uttar Pradesh
Abstract:
An experiment was undertaken on twenty genotypes and fifteen characters of Okra [Abelmoschus esculentus (L.) Moench] to evaluate variability, genotypic coefficient of variation (GCV), phenotypic coefficients of variation (PCV), heritability and genetic advance in all genotypes. The wide range of variability was observedamong fifteen characters of all genotypes. The (PCV) were generally higher than their respective genotypic coefficient of variance, thus revealing the role of environmental factors. High PCV was exhibited by plant height (14.92 %), first branching node (37.38 %), number of branches per plant (36.06 %), number of seeds per fruit (22.43 %), first fruiting node (19.07 %), first flowering node (18.03 %) and yield (16.65 %) per hectare. High GCV were observed for number of branches per plant (29.80 %), first branching node(29.75 %), number of seeds per fruit(17.30 %), first fruiting node (15.27 %) and plant height (14.51 %). High heritability coupled with high genetic advance was observed for plant height (94.0 and 29.05 %), stem diameter (94.0 and 27.81 %), fruit weight (94.0 and 21.64 %), number of branches per plant (68.0 and 50.74) and first branching node (63.0 and 48.76 %).
