[Objective] The project aims to analyze systematically what the relationship of seedset ratio with the time and place of seeding in different ecological environments is. [ Method ] Five types of female sterile line in wheat were chosen to do periodical seeding experiments in two places. [ Result ] There is a significant difference between five lines of female sterile materials and female fertility seeded in Xidi Township of Qitai County in two different periods. But there is no significant difference between female sterile line materials and female fertility seeded in Banjiegou Township in two different periods. Therefore, there is a significant difference between materials seeded in Xidi Township and materials in Banjiegou Township in conventional period, but there is no significant difference in seedset ratio of wheat in two places when the winter approaches. [Conclusion] The results presumed that the winter period sowing both in Xidi Township and in Banjiegou Township of Qitai County might improve seedset ratio of female sterile line materials.%[目的]分析不同生态环境下小麦雌性不育系雌性育性值与播期、环境之间的关系.[方法]选用5个类型小麦雌性不育材料在2个地点进行分期播种试验.[结果]在奇台西地镇种植的5个小麦雌性不育系材料两个播期对小麦雌性育性值存着显著差异,在奇台半截沟镇种植材料的两个播期对小麦雌性育性值不存着差异；在奇台西地镇与奇台半截沟镇两地种植的材料,常规播期对小麦雌性育性值存着极显著差异,而临冬播种的两地间对小麦雌性育性差异不显著.[结论]推测在奇台西地镇采取临冬播期及奇台半截沟镇种植可能提高小麦雌性不育材料的结实率.
