Abstract:
The present investigation was carried out to study the extent of heterosis and inbreeding depression through six generation mean analysis (P₁, P₂, F₁, F₂, B₁ and B₂ derived) of four crosses for yield and yield contributing character in sponge gourd [Luffa cylindrica (Roem.) L.]. The material was evaluated in a Compact Family Block Design with three replications at Main Vegetable Research Station Farm, Anand Agricultural University, Anand during Kharif 2021. The magnitude of heterosis revealed that, the cross combination ASGS 19-11 × Pusa Chikni showed positively heterosis over better and mid parent. The inbreeding depression were positively and negatively lower significant indicate that the presence of vigour in F₂.
