摘　　要：为选育高粱耐盐品种,用1.7%的NaCl溶液对51对稳定的高粱不育系和保持系进行了盐胁迫培养,通过研究其萌发期种子发芽率、相对盐害率与盐浓度之间的关系,明确高粱成对不育系和保持系之间的耐盐特性。结果表明:绝大多数保持系的耐盐性比不育系的耐盐性要好。不育系和保持系的耐盐特性不是完全一致的,不能简单的用A的抗性来表示B,反之亦然。In order to clarify the salt-tolerance relationship between the sterility line and the maintenance line of sorghum,the salt stress culture of 51 pairs was studied with 1.7% NaCl solution.The results showed that the salt tolerance of most of the maintenance lines was better than that of sterility lines.The salt resistance of sterility lines and maintenance lines was not exactly the same,and B can not be simply represented by A resistance,and vice versa.
