Advanced on Studies and Applications of Photo thermo sensitive Male Sterility in Wheat

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.
