| 摘 要： | 为探讨生态雄性不育小麦的育性转换特性，在长沙自然气候条件下，通过分期播种对生态雄性不育小麦ES－50育性转换特性进行了初步研究，结果表明，ES－50是一个有明显育性转换特性的生态雄性不育系，早播不育，晚播可育；育性转换的临界温度约为13℃，育性转换的温度敏感期为抽穗前21－13d。

| Abstract: | The mechanism of fertility alteration of ecological male sterile ES-50 was studied by means of different-sowing-dates experiment under natural climate conditions in Changsha.The results are as follows:ES-50 has evident characteristic of fertility transformation,ie, sterility when ealier sowed and fertility while later sowed .The critical temperature of ES-50 is at about 13 ℃ and the thermo-sensitive phase is 21～13 d before heading. |
