Abstract: Seventeen breeding lines (ten F4segregants along with seven parents) of bitter gourd were evaluated for twenty three characters to study its performance during late kharif season of 2018 at Department of Vegetable Science, College of Agriculture, OUAT, Bhubaneswar, Odisha, India. The experiment was laid out in randomized block design replicated thrice. All the F4segregating breeding lines of bitter gourd showed significant variations for both qualitative and quantitative characters. The overall performance on vegetative parameters indicated superiority of PhuleGreen Gold (PGG) X Priyawith respect to relatively higher vine length (4.78 m), significantly highest primary branches vine-1 (17.97) and relatively lower internodal length (6.28 cm). Similarly, F4 segregant of Hirkani Local (HL) x Tushi (45.27 days) was noted for earliness in appearance of 1st female flower. Lowest sex ratio (male: female) was recorded in Tushi x PusaDo Mousumi (PDM) (0.09). Earliest harvestable maturity wasexhibited by NakharaLocal(NL) X PDM (67.67 days) followed by NLX Priya (69.33 days) and PGG X NL (69.93 days). Significantly, longest fruit length and relatively higher fruit girth was observed in PGG X NL (10.74 cm and 12.04 cm). Heavier fruit was recorded in PGG X Priya (76.17 g). Among F4crosses, Tushi X PDM (145.13 days) showed longer crop duration. The cross between HL X Tushi (52.52) recorded highest number of fruits vine-1 and was statistically at par with Tushi X PDM (48.68) and NL X Tushi (47.37). Lower number of seeds fruit-1 was recorded in NL X Tushi (13.66). Maximum total green fruit yield vine1 was recorded in PGG X Priya (3.18 kg), closely followed by HL X Tushi (3.14 kg) and NL X Priya (2.51 kg). Significantly highest TSS (5.3 °Brix) and relatively higher ascorbic acid (108.63 mg 100g-1) was observed in PGG X NL. Based on overall findings of the present study, it can be concluded that amon F4segregants, PGG X Priya, HL X Tushi, NL X Tushi and NL X Priya are best performing segregants producing maximum total green fruit yield vine-1along with other desirable traits in bitter gourd.
