Yield losses in wheat due to heat stress are increasing with climate change, driving an urgent need for new heat-tolerant varieties; however, few resources for heat tolerance are available for use in breeding. This research aims to use comprehensive genetic and agronomic approaches to provide breeders with the tools and evidence to select WtmsDW, a newly discovered genetic region that protects pollen fertility and sustains grain yield under heat stress. These tools are expected to significantly boost productivity for the $9.8B Australian wheat industry, benefitting rural communities and industry partners and supporting food security, both directly and through longer-term extension of novel heat tolerance mechanisms to other crop species.

随着气候变化，由于热胁迫导致的小麦产量损失正在增加，迫切需要新的耐热品种;然而，很少有耐热资源可用于育种。本研究旨在利用综合遗传和农艺学方法为育种者提供选择WtmsDW的工具和证据，WtmsDW是一个新发现的遗传区域，可以保护花粉育性并在热胁迫下维持谷物产量。这些工具预计将显著提高98亿澳元澳大利亚小麦产业的生产力，使农村社区和行业合作伙伴受益，并直接或通过将新型耐热机制长期扩展到其他作物物种来支持粮食安全。
