小麦抗白粉病分子育种研究进展

Research advances in molecular breeding of powdery mildew resistance of wheat

  • 摘要: 小麦白粉病是小麦生产的主要病害之一,应用抗病品种是防治该病的十分经济、有效的措施。近年来分子标记技术的发展为小麦抗白粉病基因的研究提供了极大的方便。目前为止,小麦基因组中已定名抗白粉病主效基因有38个,其中有41个基因位点的57个抗白粉病基因被标记和作图。本文详细叙述了小麦抗白粉病基因的来源、抗病基因利用及其分子标记研究现状,介绍了国内外分子育种研究最新进展,旨在为我国抗小麦白粉病分子育种提供参考。

     

    Abstract: Powdery mildew is caused by Erysiphe graminis D.C. f. sp. tritici (Em.Marchal) and is one of the main diseases of cultivated wheat (Triticum aestivum L.). Growing resistant cultivars has proved to be an economically effective approach of controlling the disease. Molecular markers are widely used in the study on powdery mildew resistance genes in wheat. Until now, 38 resistance gene loci (Pm1~Pm38) for powdery mildew have been identified and located on different chromosomes, of which 57 loci from 41 alleles are successfully tagged or mapped. This article describes the source and utilization of powdery mildew resistance genes as well as recent research on molecular markers. Latest progress in molecular breeding of resistance to powdery mildew in wheat is discussed in detail. This study provides a reference for molecular breeding for resistance to powdery mildew in wheat.
