Abstract:
The present investigation entitled “Heterosis and combining ability studies for yield and yield contributing traits in ridge gourd (Luffa acutangula L.)” was undertaken to study combining ability for yield and yield components in ridge gourd. The experiment was conducted at Horticulture Research Scheme (Vegetable), Vasantrao Naik Marathwada Krishi Vidyapeeth, Parbhani (M.S.). The parents as well as hybrids were evaluated during Summer 2019 and 2020. An overall appraisal of GCA effects of the lines indicated that, in general, none of the line was found good general combiner for all the traits studied. However, the parent Kokan Harita was found good general combiner for majority of characters. Among testers, Arka Sumeet was found good general combiner for fruit weight. Out of 40 hybrids, the highest magnitude of positive SCA effects for fruit yield per vine was exhibited by cross JRGL-13 x Jaipur Long, IC 622917 x Utkal Tripti and IC 622920 x Arka Sumeet. These crosses also revealed good SCA effects for one or more traits.
