| 中文摘要: |
| 水稻作为我国重要的粮食作物之一，改善其稻米品质是每位育种工作者所追求的夙愿。人们对米质的要求随着生活及消费水平的增加而有所提高，目前改良稻米品质已成为育种家开展水稻品质育种的重要目标。对稻米品质性状的构成、影响米质的因素及稻米品质性状的分析技术进行了系统性的概述，将调控米质的外观品质、加工品质（粒型、垩白）、蒸煮食味品质（直链淀粉含量、糊化温度及香味）、营养品质（蛋白质）等性状相关基因的克隆、功能研究以及重要稻米品质基因在常规育种和现代育种技术上的应用进行了综述，并对稻米品质分析技术、稻米品质性状相关基因在育种上的应用进行了展望，以期为稻米品质分析技术、稻米品质的改良及品质育种提供参考，提高水稻品种的多样性，丰富水稻的种质资源。 |
| 英文摘要: |
| 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. |
