中文摘要
        利用作物杂种优势提高产量是 2 0世纪农业科学的重大创举。相对于作物杂种优势的利用来说 ,杂种优势遗传基础的研究进展缓慢。回顾了杂种优势遗传基础研究的现状与进展 ,从遗传差异、基因效应、基因表达等几个方面分析杂种优势的遗传基础 ,并对深入开展杂种优势的基础研究提出了意见和建议。
英文摘要
        Exploitation of heterosis in crops to increase yield is a pioneer work in crop production in 20th century. But the research progress on genetic mechanisms of crop heterosis falls behind the utilization of heterosis in crops. This article reviews the advances of genetic study of heterosis, the relationships between genetic diversity, gene effects, gene expression and heterosis. And some suggestions on the fundamental research of crop heterosis are provided.
