Breeding for stress-resilient crops strongly depends on technological and biological advancements that have provided a wealth of information on genetic variants and their contribution to stress tolerance. In the context of the upcoming challenges for agriculture due to climate change, such as prolonged and/or increased stress intensities, CO2 increase and stress combinations, hierarchizing this information is key to accelerating crop improvement towards sustained or even increased productivity. We propose traits with high scalability to yield and crop performance that can be targeted for improvement and provide examples of recent discoveries with potential applicability in breeding. Critical to success is the integrated analysis of the phenotypes of genetic variants across different environmental variables using modelling approaches and high-throughput phenotyping.
培育抗逆作物强烈依赖于技术和生物学的进步,这些进步为遗传变异及其对胁迫耐受性的贡献提供了丰富的信息。在气候变化给农业带来的即将到来的挑战的背景下,例如长期和/或增加的胁迫强度、CO2 增加和胁迫组合,对这些信息进行优先级排序是加速作物改良以实现持续甚至增加生产力的关键。我们提出了具有高产量和作物性能可扩展性的性状,可以作为改良的目标,并提供了一些具有潜在应用前景的最新发现的例子。成功的关键是使用建模方法和高通量表型分析来综合分析遗传变异在不同环境变量下的表型。
