摘要
水稻的许多重要农艺性状均属于数量性状,研究水稻数量性状遗传对水稻育种具有十分重要的意义。近年来大量的研究揭示了水稻QTL的基本特征,剖析了重要农艺性状的遗传基础,给水稻遗传改良带来了新策略,不断深入的研究已经完成了水稻特定数量基因的精细定位和克隆,到目前为止已经有一万多个水稻QTL进行了定位,其中有19个进行了克隆,这对水稻育种具有十分重要的意义。本文主要综述了QTL定位的理论基础,水稻QTL定位的研究进展,并对水稻QTL研究的趋势进行了展望。
Many important agronomic traits of rice belong to quantitative traits, researching rice QTL plays an important role in rice breeding. In recent years lots of studies uncovered the basic characters of rice QTL, and dissected the genetic basis of important agronomic traits, and gave some new ways to improve rice. The deepening of research has completed rice＇s specific gene clone, up to now, more than 10 000 rice QTLs have been located, and 19 QTLs have been successfully cloned, which has great significance to rice breeding. In this paper, the author summarized the theoretical basis of QTL position, the progress
