光热敏感雄性不育因其遗传基础简单、不育性和恢复性好、易于产生优良杂交组合等优点，被认为是小麦杂种优势利用最有前途的途径。综述了国内外小麦雄性不育的主要类型，即对光期和温度的响应特性、不育形态发生类型、小麦光热敏感雄性不育的遗传和分子机制以及不育系和两系杂交种的应用。讨论了该雄性不育系的遗传调控特点和杂交小麦的研究方向。
The photo-thermo-sensitive male sterility was considered as the most promising way in wheat heterosis utilizity for its advantages of simple genetic basis,good performance in sterility and restoration,and easily to produce the excellent hybridization combination.Summarizied the main types of male sterility in wheat at home and abroad were the characteristics of responding to the photo period and temperature,the types of sterility morphogenesis,the mechanism of genetic and molecular of photo-thermo-sensitive male sterility in wheat,and the applications of sterile line and two-line hybrid variety were reviewed.The character of genetic regulation and the research direction of hybrid wheat by this male sterility were discussed.
