The Scotch Whisky industry is committed to reaching net zero by 2040 and this year the Scotch Whisky Association launched its new Sustainability Strategy (SWA, 2021). With less than two decades to significantly reduce the environmental impact, 'end to end' innovative solutions are required that benefit the whole supply chain. Scotch Whisky requires high yielding and good quality malting barley, of which almost 90% is grown locally in Scotland. To maintain this requires considerable inputs, which are currently costly and unsustainable. In addition, from the production side, distillery-derived by-products require efficient and sustainable disposal. One potential solution is to use these by-products to develop new phytonutrients that can be used in the primary production of the barley crop, providing a circular sustainable growth system, reducing requirements for inputs and at the same time minimising need for disposal of waste products from distilling. Historically, seaweed and other algae have been used as a nutrient supply to grow barley on farms or crofts successfully, but to scale production to generate the quantities and quality of grain required for distilling would be impractical. We propose to examine the effects of applying these novel by-product derived nutrients on barley growth, in comparison with standard malting regime inputs, on a range of different barley cultivars which are commonly grown for malt. We will compare yield and grain characteristics, including grain nitrogen and ultimately malting quality traits. Furthermore, we will determine the effects of these nutrients on the microbiome populations of the roots and soil rhizosphere. Combining trait data gathered from initial glasshouse-controlled experiments, with genetic data generated previously, we can begin to understand the genetic control of nutrient uptake. This will allow us to identify barley cultivars that are better suited at utilising novel sources of nutrients and define potential genetic markers that can be used in downstream breeding programmes to integrate these sustainability traits. The PhD candidate will have the opportunity to exploit the long-established genetic and genomic resources available at the James Hutton Institute, gaining experience in these essential areas, along with plant & soil physiology. Importantly, they will develop skills relating to industry, specifically malting and distilling, through the close collaboration with Chivas Brothers.

苏格兰威士忌行业致力于到2040年实现净零，今年苏格兰威士忌协会推出了新的可持续发展战略(SWA，2021)。在不到20年的时间内显著减少对环境的影响，需要端到端的创新解决方案，使整个供应链受益。苏格兰威士忌需要高产和优质的麦芽大麦，其中近90%是在苏格兰当地种植的。要维持这一点，需要投入大量资金，而这些投入目前代价高昂，而且不可持续。此外，从生产方面来看，酒厂衍生的副产品需要高效和可持续的处置。一个潜在的解决方案是利用这些副产品开发新的植物营养素，可用于大麦作物的初级生产，提供一个循环的可持续生长系统，减少对投入的要求，同时最大限度地减少对蒸馏废物的处理需求。从历史上看，海藻和其他藻类一直被用作在农场或农场成功种植大麦的养分供应，但要扩大生产规模以生产蒸馏所需的数量和质量的谷物将是不切实际的。我们建议在一系列不同的大麦品种上，与标准制麦制度的投入相比较，检验应用这些新的副产品衍生的营养物质对大麦生长的影响，这些大麦品种通常用于麦芽种植。我们将比较产量和谷物特性，包括籽粒氮素和最终的麦芽品质性状。此外，我们还将确定这些营养物质对根和土壤根际微生物群落的影响。结合最初温室对照试验收集的性状数据和之前产生的遗传数据，我们可以开始了解营养吸收的遗传控制。这将使我们能够识别更适合利用新的营养来源的大麦品种，并定义可用于下游育种计划的潜在遗传标记，以整合这些可持续发展的特征。博士生将有机会利用詹姆斯·赫顿研究所建立已久的遗传和基因组资源，获得这些基本领域以及植物和土壤生理学方面的经验。重要的是，他们将通过与芝华士兄弟的密切合作，开发与工业相关的技能，特别是麦芽和蒸馏。
