小麦光温敏雄性不育转换规律研究进展

Research Advance in the Fertility Alteration of the Photo-thermo-sensitive Male Sterile Wheat

小麦光温敏雄性不育的转换规律,是二系法杂交小麦应用的前提和基础。不同的小麦光温敏不育系表现出不同的育性转换特点,包括光温敏感时期和光温转换阈值。对光温敏雄性不育小麦的育性转换规律进行了分析,以期为鉴定、筛选二系杂交小麦安全制种生态区和不育系高效繁种区提供依据。

In the thesis the research advance in the fertility alteration of the photo-thermo-sensitive male sterile wheat（Triticum aestivum L.） was summarized.Fertility alteration is the base of the two-line hybrid wheat application.Different sterile wheat showed different characteristics of fertility alteration,including the stage of photo-sensitivity and thermo-sensitivity and the critical point of temperature and day length.Definitude of fertility alteration in the photo-thermo-sensitive male sterile wheat provide foundation for breeding diffusely in different area of photo-therm^sensitive male sterile wheat line.
