Vegetable breeding generally depends on the nature and genetic components of variation. Thus it is necessary to have reliable estimates of such components in order to formulate an efficient breeding strategy. In the present study, ten diverse inbred lines were crossed to three testers viz., SP, H-8 and their F1 SP x H-8 at the Experimental Farm, Department of Vegetable Science and Floriculture, CSKHPKV, Palampur (H.P.) during kharif, 2015 to assess the nature and magnitude of genetic variability and to understand the association between different horticultural traits. Data were recorded for marketable fruit yield per plant, days to 50 per cent flowering, days to first picking, number of marketable fruits per plant, fruit length and fruit diameter. The parents (lines and testers) and their crosses were evaluated in Randomized Block Design. Analysis of variance revealed significant differences among progenies. All the characters showed significant in total epistasis. Both additive and non-additive interaction i.e., (i) type epistasis was significant for all traits except fruit length and fruit diameter whereas for (j+l) type epistasis was significant for all traits except days to first picking. Degree of dominance was in the range of partial dominance. Correlation coefficient was non-significant for all traits except marketable fruit yield per plant and days to 50% flowering. Heritability (narrow sense) estimates were low to medium.
