Exploring floral biology and hybridization in okra: advances in breeding for yield, resistance and export potential

Okra (Abelmoschus esculentus L. Moench) is a vital vegetable crop in tropical and subtropical regions, contributing significantly to both nutrition and agricultural economies. Recent advances in okra breeding leverage detailed knowledge of floral biology and hybridization techniques to achieve higher yields, improved pest and disease resistance and better suitability for export markets. This review synthesizes current progress in okra breeding, focusing on how understanding of the crop’s floral biology (e.g., timing of anthesis, pollination behaviour) facilitates more efficient hybridization and seed production. Major breeding objectives - including yield enhancement, resistance to key diseases like yellow vein mosaic virus (YVMV) and pests, improved pod quality and abiotic stress tolerance - are discussed in light of recent achievements. Conventional hybridization combined with modern tools such as marker-assisted selection and mutation breeding has led to the development of high-yielding, disease-resistant okra varieties and F₁ hybrids. Notable successes, such as YVMV-resistant cultivars and export-quality hybrids, illustrate the impact of these breeding efforts. The review also highlights the utilization of wild Abelmoschus species in broadening the genetic base and emerging biotechnological approaches (genomics and CRISPR-based gene editing) that promise to further accelerate okra improvement. Future directions emphasize the need for breeding climate-resilient, nutrient-rich okra cultivars with extended shelf life to meet global export standards. Strengthening public-private partnerships and integrating advanced molecular techniques into breeding programs will be pivotal in transforming okra into a more productive and internationally competitive crop.
