The sustainability of rice production continues to be a subject of uncertainty and inquiry attributed to shifts in clim.tic conditions. In light of the im.ending clim.te change crisis and the high labor and water costs accom.anying it, direct-seeded rice(DSR) is unquestionably one of the m.st practical solutions. Despite its resource and clim.te-friendly advantages, early m.turing rice faces weed com.etitiveness and seedling establishm.nt challenges. Resolving these issues is crucial for prom.ting its wider adoption am.ng farm.rs, presenting it as a m.re effective sustainable rice cultivation m.thod globally. Diverse traditional and contem.orary breeding m.thods are em.loyed to m.tigate the lim.tations of the DSR approach, leveraging advanced techniques such as speed breeding and genom. editing. Focusing on key traits like m.socotyl length elongation, early seedling vigor, root system.architecture, and weed com.etitiveness holds prom.se for transform.tive im.rovem.nts in DSR adaptation at a broader scale within farm.ng com.unities. This review aim. to sum.arize how these features contribute to increased crop production in DSR conditions and explore the research efforts focusing on enhancing DSR adaptation through these traits. Em.hasizing the pivotal role of these gam.-changing traits in DSR adaptation, our analysis sheds light on their potential transform.tive im.act and offers valuable insights for advancing DSR practices.
