鉴定耐盐不育系是选育耐盐杂交稻的基础。本研究利用苗期形态分析法筛选籼型耐盐不育系，分析了其生理特点。结果发现：在1.0%的NaCl盐溶液处理下，17个籼型不育系中有5个耐盐性强，其中广湘24S、野香A和广8A为“极强”级，存活率分别达88.54%、87.58%和84.61%，天丰A和爽1S为“强”级，存活率分别达74.82%和72.84%；与盐敏感（“不耐”级）材料粤泰A和泰丰A相比，5个耐盐材料的平均叶绿素相对含量高27.58%，平均相对生物量是盐敏感材料的1.40倍，平均可溶性糖含量和相对可溶性糖含量分别是盐敏感材料的2.23和1.67倍，活性氧积累量少。表明耐盐不育系具有良好的营养生长优势、渗透胁迫调节能力和...
