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.

由于气候变化而导致的小麦的产量损失正在增加，迫使人们迫切需要新的耐热品种；但是，很少有用于繁殖的耐热资源。这项研究旨在使用全面的遗传和农艺方法为育种者提供选择WTMSDW的工具和证据，这是一个新发现的遗传区域，可保护花粉生育能力并在热应激下维持谷物产量。预计这些工具将显着提高澳大利亚小麦行业的生产率，从而使农村社区和行业合作伙伴受益，并通过将新颖的耐热机制的长期扩展到其他农作物物种的长期扩展来支持粮食安全。
