Heterosis studies in okra (Abelmoschus esculentus (L.) Moench) for yield and contributing traits

Abstract

The current research on heterosis in okra (Abelmoschus esculentus (L.) Moench) utilized a half diallel approach involving nine parental lines, thirty-six hybrids and one standard check. The analysis of variance revealed significant differences among treatments for all traits examined. Heterosis was calculated as percentage differences over the better parent (BP) and the standard hybrid check (SH) for various traits. The study identified specific hybrid combinations that displayed notable positive heterosis for traits such as plant height, fruit yield, fruit length, diameter of fruit, weight of fruit and the number of branches, nodes and fruits per plant. These findings underscored the potential of certain hybrids for improving growth and yield-related traits in okra. The results indicated considerable positive heterosis in several cross combinations across different traits, with particular hybrids showing promise for further development in hybrid okra varieties. The paper concludes by recognizing promising hybrid derivatives and emphasizing their potential to enhance traits like yield, plant growth, and quality in okra farming.
