Abstract:
The present investigation entitled “Studies on genetic variability, heritability and genetic advance for fruit yield and its contributing traits in okra [Abelmoschus esculentus L. Moench] during Kharif 2019. The experiment was conducted using thirty genotypes of okra including three checks (Parbhani Kranti, Pusa Sawani and Pusa Makhmali) at Main Experimental Station, Department of Vegetable Science, Acharya Narendra Deva University of Agriculture and Technology, Narendra Nagar (Kumarganj), Ayodhya, Uttar Pradesh, India. The estimates of coefficients of variation revealed that magnitude of phenotypic coefficients of variations (PCV) were higher than the genotypic coefficient, of variation (GCV) for all the characters indicating important role of environment. The phenotypic coefficient of variation ranged from days to 50% flowering and number of fruits per plant for the various characters studied. The traits like Number of fruits per plant, fruit length (cm) showed comparatively higher values of PCV, GCV, heritability (in broad sense), genetic advance and expected genetic advance as percent of mean revealing additive gene effect and they can be improved by selection. High estimates of heritability coupled with genetic advance obtained for total fruit yield and marketable fruit yield per plant indicating presence of additive gene effects which, indicated the effectiveness of selection for these traits.
