BREEDING POTENTIAL OF SESAME FOR WATERLOGGING STRESS IN ASIA

Abstract

Sesame is an important oilseed crop in Asia that is often affected by waterlogging stress, leading to significant yield losses and reduced crop quality. Breeding waterlogging-tolerant sesame varieties is essential for ensuring the sustainable production of this crop in regions prone to waterlogging events. This review provides an overview of the challenges and opportunities associated with breeding sesame for waterlogging tolerance in Asia. We discuss the current state of sesame production in the region, sesame's physiological and morphological responses to waterlogging stress, and the genetic mechanisms underlying waterlogging tolerance. Moreover, we highlight the importance of identifying and utilizing waterlogging-tolerant sesame varieties and germplasm resources and the challenges in breeding waterlogging-tolerant sesame. Finally, we outline future perspectives for breeding waterlogging-tolerant sesame, including integrating traditional and modern breeding approaches, the potential for omics technologies and systems biology, and the role of climate-smart agriculture and sustainable management practices in mitigating waterlogging stress. By addressing these challenges, researchers and breeders can contribute to the continued success of sesame production in Asia and help to safeguard the livelihoods of millions of smallholder farmers who depend on this crop for their income and food security.
