小麦赤霉病:从表型鉴定到抗性改良

 赤霉病已成为影响中国小麦安全生产的最重要病害之一。表型鉴定体系对赤霉病抗性准确评价和抗性改良至关重要。本文分析了赤霉病的危害和改良的迫切性、中国抗赤育种的现状、QTL的定位和利用进展等，讨论了赤霉病接种鉴定和评价方法、赤霉病抗源利用和抗赤分子标记辅助育种策略，提出赤霉病改良的思路和建议。

Fusarium head blight in wheat: From phenotyping to resistance improvement

Fusarium head blight (FHB) is one of the most important diseases in wheat, which threats both food security due to huge yield losses and food safety due to the toxin accumulation. A comparison between different phenotypic evaluation methods is critically important for fine mapping and for improving FHB resistance. This paper reviews the issues including the urgency of FHB improvement, the status quo of wheat breeding for FHB resistance, and the progresses in QTL mapping for FHB and their utilization. The current phenotypic evaluation systems of FHB responses of wheat, the availability of resistance QTL donors, and the strategies of applying marker-assisted breeding approaches for improving FHB resistance are highlighted.
