Assessment Of Parental Lines and F1 Hybrids for Yield and Associated Traits in Bitter Gourd (Momordica Charantia L.)

Abstract

The present investigation was carried out to obtain information based on performances of parents and their combinations for genetic improvement in bitter gourd. thirteen (Ten line & three tester) promising genotypes were crossed in a line and tester manner (excluding reciprocals). Line & tester set of 30 F1’s and 1 check VNR-Nvadhan in bitter gourd was evaluated in Randomized Block Design (RBD) with three replications for twelve traits during zaid 2023-24 (Y1) and 2024-25 (Y2). The study evidently showed highly significant differences being observed for most of the traits under study. Based on performance, the parent V-65-1 (2.42 q/ha) found maximum for fruit yield per plant among the parents which was followed by V-198 (2.31q/ha), V-26 (2.17q/ha), NDBG-8 (1.88q/ha) and NDBG-9 (1.46q/ha). The best F1 hybrid for fruit yield per plant was V-65-1 x Arka Harit (2.95 q/ha) followed by V-65-1 x Kashi Mayuri (2.94q/ha), V-198 x DARAL-43 (2.90q/ha), V-198 x Kashi Mayuri (2.88q/ha) and V-26 x Kashi Mayuri (2.73q/ha). Based on the results, genotypes viz., V-65-1, V-198 and V-26 may be selected as parents in further breeding programme to improve the crop in terms of yield and earliness.
