Abstract: The investigation was carried out at the C.E.S. of Department of Horticulture, newlineNaini Agricultural Institute, Sam Higginbottom University of Agriculture, Technology newlineand Sciences, Naini, Prayagraj (U.P.) during Kharif season of 2017-18. The material for newlinepresent study comprised of 10 diverse lines (Azad B-4, DBR-31, Green Long, Azad B.-2, newlinePunjab Shree, Utkal Anushri, Aruna, J.B.Round, VR-2 and Punjab Barsati) and 3 testers newline(Arka Nidhi, DBR-8 and Kashi Prakash) which were selected on the basis of variability newlinefor studied characters and with their 30 crosses, developed by line x tester mating design. newlineThe experiment was carried out in R.B.D. with three replications to assess the newlineperformance of 30 F1 hybrids and their 13 parental lines. The crop was planted in rows newlinespaced at 60 cm apart with a plant to plant spacing of 60 cm. The hybrid combinations newlineVR-2 x DBR-8, Punjab Barsati x Arka Nidhi, Azad B-2 x Arka Nidhi, Utkal Anushri x newlineArka Nidhi and Utkal Anushri x DBR-8 manifested maximum heterobeltiosis and Utkal newlineAnushri x Kashi Prakash, Punjab Barsati x Arka Nidhi, VR-2 x DBR-8, Punjab Shree x newlineKashi Prakash and J.B.Round x DBR-8 manifested maximum standard heterosis for fruit newlineyield and its components. Combining ability studies revealed that good specific newlinecombinations showed high heterosis for fruit yield and majority of the yield contributing newlinetraits, high per se performance and sca effects. On the basis of sca, heterosis and gca newlineeffects, the cross combination VR-2 x DBR-8 was found to be best, followed by J.B. newlineRound x DBR-8, Utkal Anushri x Kashi Prakash and Punjab Barsati x Arka Nidhi for newlinefruit yield per plot. Since non-additive gene action is more important for all the characters newlineexcept number of primary branches, fruit length, number of flowers per plant, dry matter newlinecontent and TSS ( and#778;Brix). Heritability in broad sense was higher for all the character newlineexcept leaf length and days to 50 per cent flowering while Heritability in narrow sense newlinewas observed to be the highest for days to 50% flowering and No. of flowers per cl
