摘　　要：光温敏雄性核不育水稻的花粉育性受日照长度或温度的调控,在长日、高温条件下表现不育,短日、低温条件下表现可育。水稻这一特性的发现使得人们可以利用其进行‘两系法’杂交稻育种来补充传统的‘三系法’杂交育种体系。水稻光温敏核不育基因的研究对于‘两系法’杂交稻育种的利用研究至关重要。主要对光温敏核不育基因的遗传规律分析、基因的定位研究进展以及DAN分子标记在基因定位中的应用等方面进行了综述。A major characteristic of the Photoperiod （Thermo）-Sensitive Genic Male Sterile rice is that pollen fertility is regulated by day-length or temperature-The pollen is sterile under long-day or high temperature conditions,while it＇s fertile under short-day or low temperature conditions.Thus, it gives a new breeding way to develop ‘two-fine＇ hybrid rice to complements the traditional ‘three-fine＇ system. The study ofP（T）GMS gene in rice is very important for the utilizatioin of ‘two-line＇ hybrid rice. This study summarizes the genetic analysis ofP （T）GMS gene, the advances in the research on gene mapping of the P（T）GMS genes in rice and the application of various molecular markers on gene mapping.
