| 摘 要： | 应用不同浓度的赤霉素（GAsub]3/sub]）溶液在苗期处理CHA-1特华占原种、日本晴、矮脚南特等4个材料，研究它们对GAsub]3/sub]反应的敏感性。结果表明，经空间诱变的矮秆突变体在苗期对GAsub]3/sub]的反应敏感，但与已知带i]sd-1/i]基因的籼、粳稻代表品种矮脚南特、日本晴敏感性有差异。进一步的遗传分析表明，控制CHA-1的一对隐性矮秆基因与i]sd-1/i]基因不等位。

| Abstract: | A dwarf mutant CHA-1 obtained from a high-plant rice cultivar Tehuazhan by space inducement, and its response to gibberellic acid (GA 3) at seedling stage was studied. CHA-1 was sensitive to GA 3, but it was different to Nipponbare(japonica) and Aijiaonante(indica) (both with semidwarf gene sd-1) in sensitivity to GA 3. Further genetic analysis revealed that the mutant was controlled by a dwarf gene which was non-allelic with dwarf gene sd-1. |
