In enhancing the resilience of our crops to the impacts of climate change, selection objectives need to address increased variability in the production environment. This encompasses the effects of more variable rainfall and temperatures than currently experienced, including extreme weather events, and changes in pest and pathogens distribution with the increased likelihood of major pest and disease outbreaks as well as occurrence of novel pathogens. Farmers manage the inevitable risks associated with cropping by planting varieties that deliver high yields and good quality under optimal conditions but minimise losses when the seasons are bad. Breeders and agronomists work to support farmers in specific target environments, but increased climate variability has meant that they need to broaden the adaptability of varieties grown and increase the yield stability to help minimise climate-induced risks and build resilience.
在增强我们的作物对气候变化影响的适应能力方面，选择目标需要应对生产环境中日益增加的变异性。这包括降雨和温度比目前经历的更大的变异性影响，包括极端天气事件，以及随着主要病虫害爆发可能性增加和新病原体出现而导致的病虫害分布变化。农民通过种植在最佳条件下能实现高产和优质，但在季节不佳时能将损失降至最低的品种来管理与种植相关的不可避免的风险。育种者和农学家致力于在特定目标环境中支持农民，但气候变异性增加意味着他们需要扩大种植品种的适应性，并提高产量稳定性，以帮助将气候引发的风险降至最低并增强适应能力。
