Abstract: The investigation was carried out at the C.E.S. of Department of Horticulture, Naini Agricultural Institute, Sam Higginbottom University of Agriculture, Technology and Sciences, Naini, Prayagraj (U.P.) during Kharif season of 2017-18. The material for present study comprised of 10 diverse lines (Azad B-4, DBR-31, Green Long, Azad B.-2, Punjab Shree, Utkal Anushri, Aruna, J.B.Round, VR-2 and Punjab Barsati) and 3 testers (Arka Nidhi, DBR-8 and Kashi Prakash) which were selected on the basis of variability for studied characters and with their 30 crosses, developed by line x tester mating design. The experiment was carried out in R.B.D. with three replications to assess the performance of 30 F1 hybrids and their 13 parental lines. The crop was planted in rows spaced at 60 cm apart with a plant to plant spacing of 60 cm. The hybrid combinations VR-2 x DBR-8, Punjab Barsati x Arka Nidhi, Azad B-2 x Arka Nidhi, Utkal Anushri x Arka Nidhi and Utkal Anushri x DBR-8 manifested maximum heterobeltiosis and Utkal Anushri x Kashi Prakash, Punjab Barsati x Arka Nidhi, VR-2 x DBR-8, Punjab Shree x Kashi Prakash and J.B.Round x DBR-8 manifested maximum standard heterosis for fruit yield and its components. Combining ability studies revealed that good specific combinations showed high heterosis for fruit yield and majority of the yield contributing traits, high per se performance and sca effects. On the basis of sca, heterosis and gca effects, the cross combination VR-2 x DBR-8 was found to be best, followed by J.B. Round x DBR-8, Utkal Anushri x Kashi Prakash and Punjab Barsati x Arka Nidhi for fruit yield per plot. Since non-additive gene action is more important for all the characters except number of primary branches, fruit length, number of flowers per plant, dry matter content and TSS (˚Brix). Heritability in narrow sense was observed to be the highest for days to 50% flowering and No. of flowers per clusters and highest genetic advance in per cent of mean was observed for fruit yield per plant.
