dc.description.abstractThe present investigation was carried out at Vegetable Experimental Farm, Division of Vegetable Science and Floriculture, SKUAST, Chatha, Jammu during spring summer season of 2022. The experiment was laid out in Augmented Block Design with 100 stabilized advanced plant progenies and 5 checks (Punjab Suhawani, Palam Komal, Kashi Pragati, Kashi Vibhuti and Seli Special). Data on fourteeen yield and yield contributing characters had been recorded as per standard procedures. The analysis of variance for various characters under study showed significant differences among all plant progenies for all the characters. Data on mean performance of all the individual plant progenies revealed line 74 to be the highest high yielder followed by six lines, specifically lines 75, 76, 62, 20, 23, and 38 and also performed better for other important desirable traits viz, plant height, number of nodes per plant, number of primary branches, fruit length, fruit girth, number of seeds per fruit, average fruit weight and number of fruits per plant and these seven lines were found to be statistically superior to best check variety Palam Komal and thus, can be used for the future breeding programme. The analysis of genotypic and phenotypic coefficient variance revealed higher magnitude of PCV than the corresponding GCV for all the characters which indicated effect of environment on the character expression. Highest PCV and GCV were obtained for average fruit weight.High heritability coupled with high genetic advance was observed for average fruit weight showing the influence of additive gene action on the characters hence, may be useful for effective selection. Fruit yield per plant showed positive and significant correlation with plant height, number of primary branches, node at which first flower appear, number of nodes per plant, fruit length, fruit girth, number of fruits per plant, average fruit weight, number of seeds per fruit while fruit yield per plant showed negative and significant correlation with days to 50% flowering and days to first picking.Number of fruits per plant followed by fruit length, average fruit weight, node at which first flower appear, number of primary branches, fruit girth, number of nodes per plant, days to first picking, days to 50 % flowering showed maximum direct effect on fruit yield per plant. Genetic diversity was evaluated using D2 analysis. Six different constellations were formed comprising of 100 stabilized advanced populations and 5 checks of okra. Maximum number of plant progenies was present in Cluster 1 and Cluster IV. Maximum intercluster distance was observed between Cluster III and Cluster VI. Cluster VI had maximum mean value for characters viz., number of primary branches, internodal distance, number of fruits per plant, average fruit weight, no of seed per fruit, fruit yield per plant. This indicated that plant progenies from these clusters can be selected for specific economic character(s) for further utilization in hybridization programme.en_US
