Abstract: In order to further study rice quality to accelerate the breeding of quality and eating rice varieties(or lines)and provide the corresponding theoretical basis and technical reference, this study systematically probed into the correlation between the factors influencing the quality of rice and the synthetic evaluation value of rice. This test proposed 8 rice varieties(or lines)to determine the physical and chemical properties of rice, at the same time analyzed the appearance quality of brown rice, white rice protein containing rate, amylose content, and rice starch gelatinization characteristics index. The results show that there are different degrees of correlation between the comprehensive evaluation value and appearance quality of brown rice, white rice protein containing rate, amylose content, rice starch gelatinization characteristics, but the correlation between the physical and chemical index and the comprehensive evaluation value is not significant (P>0.05).The above results indicate that the various physicochemical indexes of rice can not accurately reflect the final taste quality.

Key words: rice, processing quality, appearance quality, nutritional quality, palatability(cooking)quality, storage quality
