摘　　要：植物杂种优势的利用是大幅度提高农作物产量最主要的措施之一,在几种主要农作物上获得了极大成功。有关杂种优势遗传理论的探讨从未间断,特别是近年来分子生物学在植物遗传领域的广泛应用,使人们对杂种优势的遗传本质有了更加深入的了解。本文综述了杂种优势遗传机理研究、杂种优势的分子生物学基础及其预测研究的进展情况。Exploitation of plant heterosis is one of the main measures to increase crop yield on a large scale. At several major crops, exploitation of heterosis has acquired great success. The genetic theory of heterosis has been explored for a long time. Accompanying extensive application of molecular biology in area of plant genetics recently, genetics of heterosis has been further understood essentially. Progress in studies on genetic mechanism, molecular basis and prediction of crop heterosis was reviewed in this paper.
