Abstract:
Heterosis studies for forty-five hybrids of okra along with their ten horticulturally sound and diverse parental lines in 10 x 10 half diallel fashion were evaluated to assess the heterosis effect over better parent and one standard hybrid check (Radhika) in Randomized Block Design with two replications in both summer and kharif seasons (2021 and 2022) for yield and yield contributing twelve characters of okra (Abelmoschus esculentus (L.) Moench). The F₁ hybrids P₁ x P₈ (RHOK 03 x RHOK 30), P₂ x P₁₀ (RHOK 12 x Phule Vimukta), P₂ x P₄ (RHOK 12 x RHOK 17), P₄ x P₆ (RHOK 17 x RHOK 23) and P₂ x P₉ (RHOK 12 x RHOK 31) displayed the significant positive heterosis for most of the traits in both summer and kharif season. The negative heterotic crosses P₂ x P₁₀ (RHOK 12 x Phule Vimukta), P₃ x P₁₀ (RHOK 14 x Phule Vimukta), P₄ x P₆ (RHOK 17 x RHOK 23) and P₆ x P₇ (RHOK 23 x RHOK 26) exhibited significant negative heterosis under summer and kharif season for length of inter-node and first fruiting node.
