This project aims to improve the selection and development of heat-tolerant wheat varieties. Heatwaves seriously reduce wheat yields worldwide, and the situation will worsen with climate variation. This project aims to apply a broad genetic scan to identify the main chromosome regions controlling heat tolerance at the sensitive flowering stage in Australian and European wheat varieties. It is expected that this knowledge will deliver crucial breeders’ tools to select heat-tolerant varieties. The project also aims to identify genes most likely to control tolerance at these chromosome locations using gene expression profiling data, trait associations and knowledge of heat-tolerance genes from other species. It is expected that these genes will reveal molecular mechanisms of heat tolerance and create new opportunities to engineer superior levels of tolerance in cereals.

该项目旨在改善耐热小麦变化的选择和发展。热浪严重降低了全球小麦的产量，这种情况将随着气候变化而导致。该项目旨在应用广泛的遗传扫描，以确定在澳大利亚和欧洲小麦变化的敏感开花阶段控制热耐受性的主要染色体区域。预计这些知识将提供至关重要的diverders工具来选择耐热品种。该项目还旨在通过基因表达数据，性状关联以及对其他物种的热耐热基因的知识来确定最有可能控制对这些染色体位置的耐受性的基因。预计这些基因将揭示出热耐受性的分子机制，并为培养谷物中的耐受性水平提供新的机会。
