Identifying climate-resilient wheat for a warmer, high CO2 world

该项目旨在揭示哪些植物性状有助于在未来几十年预测的二氧化碳和温度条件下保持或增加作物产量，从而为生产气候适应性小麦提供早期见解。小麦生产对全球粮食安全至关重要，但每升温1摄氏度，其产量就会下降5-6%。二氧化碳浓度升高可能会抵消产量损失，但会减少谷物蛋白质和营养素。作为第一项评估澳大利亚小麦在二氧化碳和温度升高的双重压力下表现的研究，该项目将提供有关小麦生产力和质量弹性性状的重要基础知识，为未来的育种计划提供新的投入，并有助于在不断变化的气候中实现粮食安全。

This project aims to reveal which plant traits help maintain or increase crop yield under the CO2 and temperature conditions predicted for the next few decades, thus providing early insights for generating climate-resilient wheat. Wheat production is vital to global food security, but its yield decreases 5-6% per 1 degree Celsius of warming. Elevated CO2 may offset yield losses, but reduces grain protein and nutrients. As the first study to evaluate Australian wheat performance under the dual pressures of elevated CO2 and temperature, the project will deliver important fundamental knowledge on wheat productivity and quality resilience traits, novel inputs for future breeding programs, and help enable food security in a changing climate.
