摘要：

小麦是我国最重要的口粮作物之一。在小麦生产所面临的各种病害中,赤霉病的发生具有愈来愈严重的趋势,引起小麦产业界的高度关注。近几十年来,科研人员在小麦抗赤霉病遗传育种以及防控技术领域进行了持续不懈的努力,在赤霉病病原菌致病基因、小麦赤霉病抗性基因定位、克隆及功能研究以及抗赤霉病分子育种等方面取得了重大进展。本文主要从赤霉病抗性基因资源的发掘和鉴定、不同抗源遗传基础解析、小麦赤霉病抗性基因、抗赤霉病分子标记辅助选择育种与基因聚合以及小麦抗赤霉病基因的克隆和功能研究等方面进行了综述,分析了目前小麦抗赤霉病研究中存在的问题,并提出应加强基因克隆、功能分子标记开发以及应用单体型辅助选择(HAS)和标记组辅助选择(MSAS)等小麦抗赤霉病研究的相关建议。

Abstract:

Wheat is one of the most important food crops in China and worldwide. Wheat production is facing the stresses of different diseases including Fusarium head blight (FHB) which is more and more serious recently and leading to highly concerns. Unremitting efforts have been made on Fusarium head blight resistance breeding and comprehensive control technology development. Rapid progress has been achieved on discovering of resistant genetic resources, mapping of resistant QTL/genes, resistant QTL/genes cloning, gene functional research and molecular breeding. In this review, we summarize the current status of the research against FHB in wheat and discuss the issues of FHB resistance investigation to date. We also suggest emphasizing on gene cloning, developing more powerful functional markers, using haplotype-assisted selection (HAS) and marker-set-assisted selection (MSAS) for further deep FHB resistance study and breeding.
