The present study was conducted at the Main Experiment Station (MES) of the Department of Vegetable Science, Acharya Narendra Deva University of Agriculture and Technology, Narendra Nagar, Kumarganj, Ayodhya (U.P.) India during the Zaid seasons of 2021-22 (Y1) and 2022-23 (Y2). Plant material consisted of 30 F1 hybrids and their 13 parents (10 lines and 3 testers) bitter gourd including 1 check namely Sagar (commercial check) in Randomized Block Design (RBD)withthreereplications in line x tester mating design. The crop was sown in rows spaced at 3 meters apart with a plant to plant spacing of 0.50 meter. Sowing was done on 22 March, 2021-22 and 19 March, 2022-23. Evaluation was done for different yield and quality traits.Observation was recorded for the 18 characters. High heritability coupled with high genetic advance were observed fornode number to first staminate flower appearance, node number to first pistillate flower appearance,vine length, fruitlength, fruit circumference, fruit weight, number of fruits per plant-1,total soluble solids, ascorbic acid, reducing sugars,non-reducing sugars, total sugar, dry matter, and fruit yield per plant-1 in both the years and pooled.High heritability (narrow sense) along with high genetic advance in per cent of mean were observed for most of important economic traits showing ample scope of crop improvement by selection.
