| 摘 要： | 以东北最新育成的三系粳稻不育系为材料,研究了海南南繁生态条件下不育系的开花习性,与在吉林生态条件下的开花习性进行比较,结果表明：不育系播种到始花的历期明显缩短,播始历期缩短17~34d,平均缩短了24.7d。不育系开花习性最明显的变化是开花时间延后,不论是始花时间、终花时间还是开花高峰在海南都比在吉林晚了1~2h,午前花率明显减少,平均减少47.4%,最高减少了81.1%。

| Abstract: | With the CMS lines newly bred in japonica hybrid rice as materials, the flowering habits of CMS lines in Jilin and Hainan ecological conditions were studied. The results showed: The period from seeding to flowering of the sterile lines was significantly shortened, cutting down the most days of 34, the least days of 15 and the average days of 23.5days. The flowering time of sterile lines was postponed 1-2h in Hainan ecological condition, compared with Jilin condition. The average flowering rate of spikelet before noon was significantly reduced 47.4%, with the most reduction of 81.1%. |
