Evaluation of growth, yield, and biochemical attributes of bitter gourd (Momordica charantia L.)

Abstract

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 2022-23 (Y1) and 2023-24 (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) with three replications 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 February, 2022-23 and 19 February, 2023-24. Evaluation was done for different yield and quality traits. In pooled, fruit yield per plant ranged from 752.12 to 2588.97 for parents and 336.89 to 2610.09 for hybrids. Parent NDBG-13 (2588.97) found to have highest fruit yield per plant among the parents which was followed by NDBG -25 (2348.75), NDBG- 35 (2238.33), NDBG-55 (1696.75). The best F1 hybrid for fruit yield per plant was NDBG-13 × PB-14 (2610.09) followed by NDBG-2 x PB-15 (2373.01), NDBG-25 x Pant Karela-1 (2356.08), NDBG-35 x Pant Karela-1 (2248.57).
