Study on genetic parameters in F4 segregating population of the cross EC 771612 × LA 2657 during Rabi 2016 for fruit yield and its attributing traits was conducted in augmented design. Results obtained Analysis of variance indicates the presence of significant variability for all the characters among F4 segregants which indicates the presence of sufficient variability. Hence the population was used estimation of variability parameters and correlation. Wider range has been observed for all the characters among the F4 segregants which imply the presence of higher phenotypic variability. Further high GCV and PCV coupled with narrow difference between PCV and GCV were found for fruits per plant, fruit diameter, plant height, clusters per plant and fruit yield per plant indicating less environmental influence on expression of characters therefore individual plant selection can be followed for improvement of these characters. High heritability coupled with high genetic advancement as a per cent of mean was observed for fruits per plant, fruit diameter, plant height, and clusters per plant and fruit yield indicating the involvement of additive gene action for expression of these traits in crosses studied. Characters like fruits per plant, plant height, fruits per clusters, clusters per plant and fruit diameter shown the presence positive significant association with fruit yield among F4 segregants which implies that fruit yield per plant could be improved up on improving some of the traits like fruits per plant, plant height, fruits per clusters, clusters per plant and fruit diameter
