Heading date, a pivotal agronomic trait determining rice production seasons and regional adaptability, is fundamental for breeding high-yield cultivars tailored to specific ecological environments. In recent years, numerous genes controlling heading date in rice have been cloned, and their functional mechanisms have been increasingly elucidated. Consequently, the molecular regulatory network governing heading date has become progressively refined. This review systematically summarizes the molecular mechanisms regulating rice heading date, with a focus on the photoperiodic regulatory network, and discusses its applications in breeding practices. It aims to provide a theoretical foundation for the genetic improvement of heading date and ecological adaptability breeding in rice.
Key words： rice; heading date; molecular mechanism; breeding
