摘　　要：水稻是一种对盐浓度中度敏感的作物,耐盐性状是受多基因控制的数量性状,易受环境条件等影响,目前定位的耐盐QTL主要为苗期耐盐相关的,其中以第1、2、6和7染色体上居多。耐盐品种的选育方法主要为系统选育法,将杂交选育和胁迫组织培养、转基因等生物技术相结合,选育耐盐性强且品质优良的品种。本文阐述了国内外开展的关于水稻耐盐基因遗传及耐盐育种研究动态,并对今后耐盐育种的工作提出了展望。Rice is a kind of moderate-sensitiveness crop to salt, salt-tolerance characters belong to quantity character was controlled by polygene, and it is easy to be affected by environment etc. At present, salt tolerance QTLs which located in first, second, sixth, seventh chromosome mostly were correlative to seedling salt tolerance; Salt tolerance varieties were cultivated by systemic selection, cross selection, stress tissue culture and identification; and the research future prospects in the future was discussed.
