Abstract:
The present study on heterosis in okra (Abelmoschus esculentus (L) Moench) conducted using a half diallel method with seven parents, twenty-one hybrids, and one standard check. The analysis of mean squares showed significant differences due to treatment for all the studied traits. Heterosis was estimated as percentage values over the better parent (BP) and standard hybrid checks (SH) for various characters. The study identified specific cross combinations that exhibited significant positive heterosis for traits such as plant height, fruit yield, length of fruit, and number of branches per plant. The results also highlighted the potential of certain hybrid derivatives for the improvement of growth and yield-related characteristics in okra. The results indicated significant positive heterosis in several cross combinations for different traits, with specific hybrids showing potential for further exploitation in the development of hybrid okra varieties. The paper concludes by identifying promising hybrid derivatives and highlighting their potential for enhancing traits like yield, plant growth, and quality in okra cultivation.
