 ABSTRACT

The present Investigation was carried out to study the extent of heterosis, inbreeding depression and heritability through six generation mean analysis ( P1, P2, F1, F2, BC1 and BC2 derived) of three crosses for yield and yield contributing character in ridge gourd (Luffa acutangula L.). The material was evaluated in a Randomized Block Design with two replications during summer 2018. The magnitude of heterosis revealed that, the cross combinations Konkan Harita x Arka Sujat and Krishna-51 x Kranti-30 showed significant heterosis over better and mid parent. The inbreeding depression were positively and negatively lower significant indicate that the presence of vigour in F2, Heritability was observed important for crop improvement of yield contributing character, high to low for different characters and play important role in selection of population for crop improvement in ridge gourd.

Key words: Generation mean, Heterosis, Inbreeding depression, Heritability.
