水稻育种计划需要重点开发营养密集型水稻，以增加价值并帮助减少营养不良。与矿物质和维生素缺乏有关的问题在大多数人口中很常见，在发展中国家更是如此，因为他们的主食是大米。水稻营养品质的基因和QTL是近年来发现的。本文通过广泛的文献调查和公共领域数据库，对籽粒蛋白质和氨基酸含量、维生素和矿物质、血糖指数、酚类和类黄酮化合物、植酸、锌和铁含量等营养性状及其相关的QTL进行了综述。此外，还讨论了通过转基因和先进的基因组方法取得的成就。以图表形式概括了与微量营养元素和氨基酸含量增加有关的基因和/或QTL的信息。将相容的QTL/基因组合在一起可以设计出在多个品质性状上具有上级优势的基因型。本文的综述将有助于将分子标记和转基因辅助育种技术与传统育种相结合，培育营养密集型水稻品种。
Rice breeding program needs to focus on development of nutrient dense rice for value addition and helping in reducing malnutrition. Mineral and vitamin deficiency related problems are common in the majority of the population and more specific to developing countries as their staple food is rice. Genes and QTLs are recently known for the nutritional quality of rice. By comprehensive literature survey and public domain database, we provided a critical review on nutritional aspects like grain protein and amino acid content, vitamins and minerals, glycemic index value, phenolic and flavonoid compounds, phytic acid, zinc and iron content along with QTLs linked to these traits. In addition, achievements through transgenic and advanced genomic approaches have been discussed. The information available on genes and/or QTLs involved in enhancement of micronutrient element and amino acids are summarized with graphical representation. Compatible QTLs/genes may be combined together to design a desirable genotype with superior in multiple grain quality traits. The comprehensive review will be helpful to develop nutrient dense rice cultivars by integrating molecular markers and transgenic assisted breeding approaches with classical breeding.
