| 摘 要： | 综述了分子标记在玉米产量QTL和杂种优势遗传基础方面的概况。对玉米产量QTL的研究方法，QTL数目、位置和遗传效应及应用作了介绍。比较了多种利用QTL结果对杂种优势的解释。作者认为，杂种优势的产生是显性效应，超显性效应和上位性效应共同作用的结果，不可能只是一种基因效应在起作用。并提出杂种通过自组织理论而形成的最优基因表达调控是杂种优势形成的理论基础。

| Abstract: | Progress in studies on maize yield QTL and the genetic theoretical basis of hetero- sis by using molecular markers are reviewed.In this paper,the methods of measured on maize yield QTL,QTL number and position,their genetic effect and application were intro- duced;various explanations of heterosis based on QTL were compared.However,We think that heterosis is caused by the complex effects of dominance,over-dominance and epistasis. It was suggested the theoretic basis of heterosis results from best-optimum gen... |
