| 利用优异基因资源改良小麦抗旱性是应对干旱和保障粮食安全的重要途径。结合国内外小麦抗旱性研究的最新进展和本研究组的研究实践，概述了现行主要抗旱性鉴定方法的适用对象和评价指标，以及小麦抗旱种质创新、抗旱基因资源发掘与利用等方面的研究成果，同时提出未来小麦抗旱性研究的重点任务和发展方向，即建立基于高通量表型鉴定的抗旱性综合评价技术体系，建立基于高通量基因型鉴定的抗旱基因资源发掘平台，创建基于综合运用多学科技能的智慧育种策略，以期为加快小麦抗旱性遗传改良提供信息资源和理论参考。 |
| 英文摘要: |
| Improving drought resistance of wheat with elite genetic resources is an important strategy to cope with drought stress and ensure food security. Based on the recent progress of wheat drought resistance research at domestic and abroad and our research practices, this paper summarized the applicable objects and evaluation criteria of the current main methods for drought resistance identification,the research achievements in the germplasm enhancement of drought resistance and discovery and utilization of genes regulating drought resistance. The key tasks and directions of wheat drought resistance research in the future have been proposed in this study, which is to establish a comprehensive evaluation technology system for drought resistance based on high\|throughput phenotyping strategy as well as an exploration platform for genes regulating drought resistance based on high\|throughput genotyping strategy. Researchers also suggest creating intelligent breeding strategies based on integrated utilization of multidisciplinary skills to provide information resources and theoretical guidance for accelerating the genetic improvement of wheat drought resistance. |
