Okra (Abelmoschus esculentus L. Moench) is a vital vegetable crop with significant nutritional and economic importance in tropical and subtropical regions. Investigating heterosis in okra is crucial for improving yield, quality and resistance to biotic and abiotic stresses, resulting in superior hybrids with enhanced traits. As an often cross-pollinated crop, okra offers great potential for heterosis exploitation. This study, conducted at the Vegetable Experimental Farms II, Division of Vegetable Science, Sher-e-Kashmir University of Agricultural Sciences and Technology of Jammu, during 2022–2023, evaluated heterosis in okra to develop high-yielding, resilient cultivars. Seven parental lines and three testers were crossed in a Line × Tester design F1 cross combinations, parents and check were evaluated using a randomized complete block design in three replications. Significant differences among parents and hybrids were observed for all traits under study. Crosses like Arka Abhay × Punjab-20, Pusa Bhindi-5 × Punjab-20 and Arka Abhay × JBS-02 showed heterosis for earliness traits such as days to 50% flowering and days to first picking. Promising crosses, including Arka Abhay × Arka Lushgreen and Arka Anamika × JBS-02, exhibited heterosis for traits such as days to 50% flowering, first flowering node, inter-nodal distance and number of fruits per plant. These findings form the basis for developing superior okra hybrids with enhanced yield and quality. Identified hybrids can undergo multi-location trials to validate their performance before potential release, offering benefits to farmers, improving food security and meeting market demands efficiently.
