Food shortages have once again become a serious problem, not only because of world population growth but also as a result of escalating demand for crops as a substrate for biofuels. The production of improved plant varieties, especially major crops such as rice, is urgently required to increase yield. The completion of the sequencing of the rice genome has made it possible to clone and analyze quantitative trait loci (QTLs). Furthermore, the development of high-throughput sequencing and genotyping technologies has improved spectacularly the accuracy of QTL analysis. In this review article, we focus on the potential roles of major QTLs in the selection for agronomic traits in rice and discuss the application of high-throughput technologies for high-resolution genetic analysis.
粮食短缺再次成为一个严重的问题，不仅是因为世界人口增长，还因为作为生物燃料原料的作物需求不断增加。急需生产改良的植物品种，特别是水稻等主要作物，以提高产量。水稻基因组测序的完成使得克隆和分析数量性状位点（QTL）成为可能。此外，高通量测序和基因分型技术的发展极大地提高了 QTL 分析的准确性。在这篇综述文章中，我们重点讨论了主要 QTL 在水稻农艺性状选择中的潜在作用，并讨论了高通量技术在高分辨率遗传分析中的应用。
