摘要
由于杂种优势的利用是农业增产的重要途径,杂种优势的遗传基础研究一直受到高度重视.近十年来发展的分子标记技术及构建的高密度遗传图谱,为阐明杂种优势的遗传基础提供了有力的工具,杂种优势研究有了新进展.通过对已有资料的分析研究,从遗传差异、基因表达调控、基因效应、基因网络系统等方面探讨了杂种优势的遗传基础及其研究进展.
Exploitation of heterosis in crops to increase yield is a pioneer work in crop production in 20th century. In recent ten years, with the development of molecular marker techniques and genetic map in high densities, there has been rapid progress in research of genetic basis of heterosis. In this paper, the genetic basis of heterosis is analyzed from genetic difference, gene expression, gene effects, and gene network system. Furthermore, the research progress is summarized.
