Abstract: The estimated value of additive genetic component was significant for all characters- days to flowering, height of plant, number of branches per plant, length of leaf, width of leaf, length of fruit, width of fruit, number of fruit per plant, width of fruit, number of fruit per plant, weight of fruit and fruit yield per plant. The value of was observed higher than the and additive genetic component for all the traits. The estimates of dominant component  was also higher than additive genetic component for all the traits except width of fruit. The estimated value of  was found positive and significant all the characters except four characters plant height, number of branches per plant, length of fruit and fruit yield per plant. The estimated value of was found to be positive and significant for all the characters except for days to flowering number of branch per plant, length of leaf, length of fruit, and width of fruit. The estimated value of was found to be non significant for all the characters except of dominance  reflected over dominance for all the characters. The computed ratio of   being less than unity for all characters except days to flowering, length of leaf, width of leaf, width of fruit.
