Abstract
Rice is one of the most widely consumed cereal crops and staple food for more than half of the world's population, especially in Asian countries (Li and Cui, 2014). The growth period of rice is an important agronomic trait, which determines the planting regions or adaptabilities of rice varieties. In breeding practice, there is often a contradiction between high yield and early maturity (Wang et al., 2018a), meaning that a variety with higher yield usually has a longer growth period. Thus, breeding varieties with early maturity and high yield has been one of the main directions of genetic breeding programs.
