Abstract: The protein content was one of main index that measures the rice nutrition value, so that improving the protein content was important target for nutrition quality breeding in rice.This paper described the protein type, amino acid’s constitute and the nutrition value in rice. Meanwhile the paper summarized the difference among genotype of rice and different part or organization of brown rice, the enviroment’s influence on the protein content, the genetic and molecular mechnasim research of the protein content, which will provide the basis for the protein research and prebreeding for high protein rice .

Key words: Rice, Protein content, Genetic, Molecular, Breeding
