Abstract:

Rice is one of the three main grain crops in China,and it is also one of the guaranteed varieties to ensure the absolute safety of rations in China,thus it has high production value. With the rapid development of technologies such as molecular markers and transgenic technology,more and more researchers have focused on cloning and identifying genes for high yield,high resistance,high nutritional efficiency and other excellent agronomic traits in rice. On this basis,molecular breeding technology is used to improve the target traits in order to obtain rice varieties with excellent comprehensive traits. Compared with traditional hybridization techniques,the application of molecular breeding in rice can break the reproductive isolation between species and shorten the breeding time,therefore make the improvement of rice traits more precise and diversified. This article reviews the recent research progress on the regulation genes related to high nutrient utilization efficiency,hormone,biotic stress,abiotic stress,yield and quality in rice,and prospects on the future direction of rice research and development,aiming to provide a beneficial reference for the scientific research of rice in China.
