水稻数量性状（QTL）定位主要作图群体及统计方法概述

摘要

Most of the important agronomic are quantitative traits in rice, which are controlled by polygenes. Therefore the research of quantitative character to promote the rice yield, disease resistance, good quality is of great significance. The rapid development of molecular biotechnology and the emergence of mapping methods were the basic of the research of many important agronomic traits in rice. The principle, population and main analysis methods were brielfy introduced in this paper. The author also summarized the problems and prospects of mapping QTLs for rice yield traits.%水稻许多重要的性状是由多基因控制的数量性状，因此数量性状的研究对促进水稻高产、抗病、质优具有重要意义。分子生物技术的迅速发展和 QTL定位方法的日趋完善，为水稻数量性状的研究提供了基础。综述了QTL定位的原理、定位群体和常用的方法，并对目前水稻数量性状QTL定位存在的问题和发展前景进行了探讨。
