Abstract: The present investigation entitled “Variability analysis in Okra (Abelmoschus esculentus (L.) Moench)” was carried out at three different locations viz., Vegetable Experimental Farm, Division of Vegetable Science, SKUAST-K, Shalimar (E1), Regional Research Station and Faculty of Agriculture, Wadura (E2) and Mountain Research Centre for Field Crops, Khudwani (E3) to study the extent of genetic variability present in the materials. The observations were recorded on days to first flowering, days to first fruit picking, plant height (cm), number of nodes plant-1, internodal length(cm), pod length(cm), pod girth(cm), pod weight(g), number of pods plant-1, pod yield plant-1(g), number of seeds pod-1, 100 seed weight(g), seed yield plant-1 and pod yield(t/ha). Analysis of variance revealed highly significant differences among parents and crosses for all traits in all environments as well as in pooled analysis indicating that the materials used for the present study were diverse. For all the traits, the significant interaction of genotypes with environments revealed that the genotypes behaved differently under different environments. The parents x environment and crosses x environment interaction were also significant for all the traits indicating that parents and crosses behaved differently under different environments with respect to these traits. Genotypic coefficients of variation were closely associated with their corresponding phenotypic coefficients of variation indicating that the traits were less affected by the environment. High to moderate values of PCV and GCV were suggestive of the fact that there is wide scope for the improvement of such traits. The genotypic coefficient of variation was highest for pod yield per plant.
