| Abstract: |
| Rice is one of the most important crops in China, and the improvement of its grain quality is the wish of every breeder. With the improvement of living standard and consumption level, people's demands for rice grain quality are also increasing. At present, improving rice quality has become an important goal for breeders to carry out rice grain quality breeding. The composition of rice grain quality traits, factors affecting rice quality and analysis technology of rice grain quality traits were systematically introduced. The cloning and functional studies of genes related to rice appearance quality, processing quality（grain shape, chalkiness）, cooking and eating quality（amylose content, gelatinization temperature and fragrance）, nutritional quality（protein）, and applications of important rice grain quality genes in conventional and modern breeding technologies were summarized. The analysis technology of rice quality and the application of rice grain quality trait related genes in breeding were prospected in order to provide references for rice quality analysis technology and the improvement of rice quality and quality breeding, improve the diversity of rice varieties and enrich rice germplasm resources. |
