| 摘 要： | 为了鉴定水稻籼型不育系在不同生育阶段的耐盐性，筛选出适合耐盐杂交水稻新组合测配的强耐盐不育系，笔者分别在萌发期、幼苗期对8个水稻籼型不育系进行耐盐性鉴定，以耐盐品种FL478、盐敏感品种IR29为对照。结果显示：盐胁迫对水稻种子的萌发起到抑制作用，抑制效应随盐浓度的提高而增强，10 g/L NaCl浓度胁迫能较好反映水稻不育系萌发期耐盐性的差异。‘沪旱7A’、Y58S在萌发期的耐盐性最好，与FL478均属于1级，具极强的耐盐性；‘荃9311A’的盐害级别为3级，具强耐盐性。盐胁迫对水稻幼苗的生长也起到明显的抑制作用，8 g/L NaCl浓度胁迫下的枯叶率性状能较好反映水稻不育系幼苗期耐盐性的差异，‘沪旱11A’与耐盐对照FL478耐盐性相仿。

| Abstract: | In order to identify the salt tolerance of indica male sterile lines in different development stages and screen out the appropriate male sterile lines with high salt-tolerance for further hybrid rice combination, 8 indica male sterile lines were identified for salt tolerance during germination and seedling stages, FL478 and IR29 were used as positive and negative controls, respectively. The results showed that the germination of rice seeds was inhibited by salt stress, and the inhibiting effect was enhanced with the increase of salt concentration. 10 g/L NaCl could be selected as the best concentration for salt-tolerant identification, the tolerant differences among lines were obvious under this concentration in germination stage. ‘Huhan 7A’ and Y58S revealed the best salt tolerance during germination stage, which belonged to the first salt-tolerance level just like FL478. Meanwhile, ‘Quan 9311A’ also showed strong salt tolerance which belonged to level 3. The growth of rice seedling was also inhibited by salt stress, and the percentage of withered leaves under 8 g/L NaCl could be used as an index to reveal the salt-tolerance level during seedling stage. Salt tolerance of ‘Huhan 11A’ was similar to that of the positive control FL478. |
