The formation of rice fragrance is a complex and changeable physiological process, and affected by genetic and environmental changes. The fragrance is mainly controlled by the fragrance gene BADH2. Climate, soil and cultivation conditions also directly affect the synthesis of fragrance compounds in rice. In order to further accelerate the breeding process and improve the quality of fragrant rice. We reviewed recent research progresses in the genetic and physiological mechanisms of the formation of fragrance compounds in rice and the effects of environmental factors on its formation in this manuscript. The effects of light, water, temperature, fertilizer and mineral elements on rice fragrance synthesis were particularly summarized. Meanwhile, the future research directions were pointed out to provide a reference for improving the cultivation techniques and quality of fragrant rice in China.
Key words： rice; fragrance; 2-acetyl-1-pyrroline; fragrant rice
