Abstract： Water-saving and drought-resistance rice （WDR） is an emerging crop type that combines the high yield and good quality of paddy rice with the water-saving and drought-resistance characteristics of upland rice. This paper systematically summarized the breeding theories， variety development strategies，and application outcomes of WDR in marginal lands， including waterlogged drylands， reclaimed wasteland， and saline-alkali soils.The keys of cultivation technology were summarized focusing on dry direct-seeding with aerobic cultivation. In response to current promotion challenges， future development directions were proposed， focusing on fundamental research，breakthrough variety breeding， integrated greencultivation techniques，and wholeindustry-chain collaboration. This review aims to provide theoretical and practical guidance for WDR research and industrialization.

Keywords： Water-saving and drought-resistance rice; Direct seeding; Aerobic cultivation; Molecular breeding; Marginal land
