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。你的工作将集中在当前育种计划中啤酒和威士忌的麦芽质量，特别是植物和谷物发育期间环境热应激的影响。该项目将使用受控环境和温室工作，并在生理/遗传研究中进行田间试验，以确定赋予气候稳定性的特征和控制它们的遗传变异。这项调查将利用位于先正达的JHI现场和设施的IBH微麦芽实验室来剖析对麦芽质量的影响。这项制麦工作将专注于已知的麦芽质量与环境和遗传背景的复杂相互作用，同时专注于具有理想麦芽质量的优质材料。该项目的这一方面包括有机会更详细地研究气候变量对淀粉和其他多糖在谷物中沉积的影响，以及随后对麦芽质量的影响。我们鼓励对植物遗传学和现代植物育种感兴趣的学生申请。博士学位提供了相当多的培训机会，包括在工业界的就业机会。背景由于气候变化，年度天气模式的变异性正在增加。在2020/21生长季节，英国春季的平均气温很高，超出了30年来的范围，在2021/22收获年度，记录了创纪录的夏季气温。气候模型表明，这些波动和极端情况可能会继续下去，甚至会恶化。这些环境胁迫不仅对作物产量和产量构成因素有明显影响，而且对麦芽品质也有明显影响。制麦是一个工业过程，依赖于摄入统一质量的大麦作物来进行高效和均匀的加工。气候的这些波动给制麦业和大麦供应链带来了巨大的挑战。然而，有证据表明，一些大麦品种的麦芽品质似乎比其他品种对气候变化的耐受性更强。这表明，有机会培育出在未来一系列气候情景下保持麦芽品质的大麦品种。
