Abstract:

Chalkiness is one of the important indexes to evaluate the appearance quality of rice. It is a bad character that seriously affects the grinding, appearance and taste quality of rice, and plays an important role in the market value evaluation of rice. This paper summarized the effects of environmental factors, physiological mechanisms and genetic mechanisms on the formation of chalkiness in rice, and pointed out the difficulties existing in the improvement of chalkiness in rice breeding. Based on the current research results and the development of related technologies, some suggestions for improvement were put forward to provide a certain research basis for the production of high-quality rice.

Key words: rice, chalky, genetic mechanism, formation mechanism, cultivation conditions
