Six generation mean analysis was carried out to investigate the inheritance of yield traits (Fruit length, fruit equatorial diameter, number of fruits per vine, average fruit weight, fruit yield per vine, number of seeds per fruit and hundred seed weight) using two crosses of bottle gourd viz., IC342079 × IC4211962 and Arka Bahar × IC4211962, parents, F1, F2, B1 and B2 generation in the kharif season of 2023 at Kittur Rani Channamma College of Horticulture, Arabhavi, Belagavi district (Karnataka), India. Results indicated that dominance × dominance gene effect was predominant in cross IC342079 × IC4211962 for average fruit weight and fruit yield per vine. Whereas, additive, additive x dominance and dominance × dominance gene effect were predominant in cross Arka Bahar × IC4211962 for average fruit weight. For fruit yield per vine additive × dominance and dominance × dominance gene interactions in cross Arka Bahar × IC4211962 were found predominant.

Lagenaria siceraria, Gene effects, Epistasis, Gene interactions, Generation Mean Analysis

Generation mean analysis and heterobeltiosis in conjunction with negligible inbreeding depression, revealed presence of fixable gene action with interactions for yield suggesting simple selection or pedigree selection. Traits showing complex inheritance can be improved through reciprocal recurrent selection or by intermating with in the population.
