In this project the student will investigate the impact of climate variation on barley using modern genetic and genomic techniques. Your work will focus on malting quality for beer and whisky in a current breeding programme, in particular the effect of environmental heat stress during plant and grain development. This project will use controlled environment and glasshouse work, and field trials in a combined physiological/genetic study to identify the traits that confer climatic robustness and the genetic variants that control them. This investigation will dissect the effect on malting quality using the IBH micromalting lab on the JHI site and facilities in Syngenta. This malting work will focus on the known complex interactions of malting quality with environment and genetic background whilst concentrating on elite material with desirable malting quality. This aspect of the project includes the opportunity for more detailed studies into the effect of climatic variables on deposition of starch and other polysaccharides in the grain, and the subsequent impact on malting quality. Applications are encouraged from students with an interest in plant genetics and modern plant breeding. The PhD offers considerable training opportunities including placements with industry. BackgroundDue to climate change the variability in annual weather patterns is increasing. In the 2020/21 growing season average UK spring temperatures were high, outside the 30-year range and in the 2021/22 harvest record summer temperatures were recorded. Climate models suggest these fluctuations and extremes are likely to continue and indeed worsen. There is a clear impact of these environmental stresses on crop yield and yield components, but also on malting quality. Malting is an industrial process and relies on an intake of a uniform quality barley crop for efficient and homogenous processing. These fluctuations in climate present a significant challenge to the malting industry and the barley supply chain. However, there is evidence that the malting quality of some barley varieties appears to be more robust to climate variation than others. This indicates that there is the opportunity to breed barley varieties that retain malting quality across a range of future climate scenarios.

在这个项目中，学生将使用现代遗传和基因组技术研究气候变化对大麦的影响。您的工作将集中在当前繁殖计划中的啤酒和威士忌麦芽质量上，尤其是在植物和谷物开发过程中环境热应激的影响。该项目将使用受控的环境和温室工作，并在合并的生理/遗传研究中进行现场试验，以确定赋予气候鲁棒性的性状和控制它们的遗传变异的特征。这项调查将使用JHI站点和先正达的设施上的IBH微型实验室来剖析对麦芽质量的影响。这项麦芽作品将集中于麦芽质量与环境和遗传背景的已知复杂相互作用，同时以理想的麦芽质量专注于精英材料。该项目的这一方面包括有机会进行更详细的研究，以了解气候变量对谷物中淀粉和其他多糖沉积的影响以及随后对麦芽麦质量的影响。鼓励对植物遗传学和现代植物育种感兴趣的学生进行应用。博士提供了相当大的培训机会，包括与行业的安置。气候变化的背景日在年度天气模式中的变化正在增加。在2020/21的生长季节，英国平均春季温度很高，超出了30年的范围，并记录了2021/22收获创纪录的夏季温度。气候模型表明，这些波动和极端可能会持续下去，并且确实恶化了。这些环境压力对作物产量和产量成分有明显的影响，但也对磨损质量产生了影响。麦芽是一个工业过程，依赖于均匀质量的大麦作物的摄入量来进行高效且同质的加工。气候中的这些波动对麦芽业和大麦供应链带来了重大挑战。但是，有证据表明，某些大麦品种的麦芽麦质量似乎比其他大麦的气候变化更健壮。这表明有机会在一系列未来的气候场景中繁殖大麦品种。
