The success of vegetable breeding operations mainly depends upon the nature and extent of genetic components of variation. Thus it is imperative to have reliable estimates of such components in order to formulate an efficient breeding strategy. In the present study, the components of genetic variation were studied in AN (Arka Nidhi) and SN (Singh Nath) for quantitative characters. The estimates of both additive and dominance components were significant for all the characters except days to 50 per cent flowering, fruit diameter, number of branches per plant and pedicel length. Epistasis (i) and (j+l) type was significant in all the traits except except fruit diameter (cm). The degree of dominance (H/D)1/2 was in the range of over dominance for marketable fruit yield per plant, number of marketable fruits per plant, fruit length (cm), plant height (cm), number of branches per plant and fruit weight (g) where as the presence of partial dominance for days to 50 per cent flowering, days to first picking, fruit diameter (cm) pedicel length (cm) and bacterial wilt incidence.
