With the aim to elucidate the components of genetic variation which will be of major importance in selection of parental genotypes and planning an appropriated hybridization programme for okra improvement. The present study was carried out at Department of Vegetable Science and Floriculture, CSKHPKV, Palampur, Himachal Pradesh, involving the 45 F1 hybrids developed through diallel matting excluding reciprocals consisting of 10 diverse okra genotypes as parents. The elucidation of different genetic components and ratios were done upon 11 different traits that included, growth, earliness, yield and quality traits of okra. It was noticed that all the traits studied were influenced mainly by non-additive gene actions and the expression of the traits were found to be genetically controlled by over-dominance effects. The narrow sense heritability for most of the traits was found to be very low that supported the findings of the component estimation. Hence, it is concluded that the hybridization followed by selection will be of great help in improvement of these traits in okra under mid-hill regions of Himachal Pradesh.
