Completion of the genome analysis followed by extensive comprehensive studies on a variety of genes and gene families of rice (Oryza sativa) resulted in rapid accumulation of information concerning the presence of many complex traits that are governed by a number of genes of distinct functions in this most important crop cultivated worldwide. The genetic and molecular biological dissection of many important rice phenotypes has contributed to our understanding of the complex nature of the genetic control with respect to these phenotypes. However, in spite of the considerable advances made in the field, details of genetic control remain largely unsolved, thereby hampering our exploitation of this useful information in the breeding of new rice cultivars. To further strengthen the field application of the genome science data of rice obtained so far, we need to develop more powerful genomics-assisted methods for rice breeding based on information derived from various quantitative trait loci (QTL) and related analyses. In this review, we describe recent progresses and outcomes in rice QTL analyses, problems associated with the application of the technology to rice breeding and their implications for the genetic study of other crops along with future perspectives of the relevant fields.
完成水稻（Oryza sativa）基因组分析后，对其各种基因和基因家族进行广泛深入的研究，使得关于这种全球种植的最重要作物中许多复杂性状的信息迅速积累，这些性状由许多具有不同功能的基因控制。对许多重要水稻表型进行遗传和分子生物学剖析，有助于我们理解这些表型遗传控制的复杂本质。然而，尽管该领域取得了显著进展，但遗传控制的细节在很大程度上仍未解决，从而阻碍了我们在培育新水稻品种时利用这些有用信息。为了进一步加强目前已获得的水稻基因组科学数据的田间应用，我们需要基于来自各种数量性状位点（QTL）及相关分析的信息，开发更强大的基因组辅助水稻育种方法。在本综述中，我们描述了水稻QTL分析的最新进展和成果、该技术应用于水稻育种所涉及的问题及其对其他作物遗传研究的启示，以及相关领域的未来展望。
