ABSTRACT
The present study was conducted to assess the magnitude of variability among twenty-four different quantitative traits in Okra germplasm. The analysis of variance revealed high significant differences for all characters under study. High GCV and PCV noticed for YVMV Infestation on Fruits, Co-efficient of YVMV Infection, YVMV Infestation on Plants, Severity of YVMV Infestation, FSB infestation on fruits, marketable yield/plant, FSB infestation on shoots, total yield/plant, marketable fruits/plant, branches/plant, leaves/plant and seeds/fruit. High heritability (h2 bs) was observed for all characters studied. High genetic gain coupled with high heritability recorded for YVMV Infestation on Fruits (%), Severity of YVMV Infestation, Co-efficient of YVMV Infection, FSB infestation fruits, marketable yield/plant, FSB infestation on shoots, total yield/plant, marketable fruits/ plant, branches/plant, leaves/plant, seeds/fruit, fruits/plant, fruit weight, 100 seed weight, plant height, internodal distance and first flowering node indicating the role of additive genetic variance in the expression of these traits. Thus, these traits may serve as an effective selection parameter during breeding programme for crop improvement. Based on the mean performance for pod yield, yield component traits and relative resistance to YVMV and FSB, genotypes 2012/OKYVRES-5, 2012/OKYVRES-6, 2012/OKYVRES-2, 10/OKYVRES-2 and 10/OKYVRES-3 found superior in performance than check varieties. These could be used as parental material in further crop improvement program after considerable selection to fix the desirable traits.
Key words: Okra, genetic variability, heritability, genetic gain, Yellow vein mosaic virus.
