| 摘 要： | 通过大田分期播种,对温敏不育系“417S”在云南元江（23°36'N）4个不同海拔试点自然条件下的育性表达及其转换作了观察鉴定。结果表明,在元江自然条件下,“417S”表现明显的育性转换,其育性转换主要受温度控制,与光照长度相关不显著。该不育系在自然条件下的育性表现与人工控制条件下虽有差异,但基本上表现一致。

| Abstract: | The fertile expression and change of the TGMS rice line “417S”, seeded at different times. were observed and indentified under the natural conditions of four different altitude tested locations in Yunjiang. The results showed that “417S” line demonstrated obviusly the fertile change, which was controlled mainly by temperature and had no significant correlation with the light length. The fertility expression showed fundamentally consistant between the natural and the artificial conditions. |
