Short Rotation Coppice (SRC) willow (genus Salix) is amongst the most advanced second generation energy crops in temperate regions. Breeding and improvement of this crop has been significantly enhanced by underpinning with genetic and genomic approaches led by two independent leading programmes in the UK and Sweden. To further advance the crop, cultivars are needed that will grow on a wider range of environments and that are future climate proof. The research proposed here will increase the effectiveness of public research supporting the genetic improvement of willow for Short Rotation Coppice in Europe by combining the two leading efforts and targeting them towards these goals. It will do this by taking shared approach to the delivery of key underpinning research, developing and sharing key research and genetic resources, and by working proactively and collectively with stakeholders to deliver this research into practice. The research brings together Europe's leading publicly funded research based SRC willow genetic improvement and public breeding programme based at Rothamsted (UK) with the long-standing Swedish willow breeding effort at the Swedish University of Agricultural Sciences and at Uppsala; Lantmännen/Agroenergi AB as the premier private sector marketer of willow in Europe; and the expertise in phenotyping, science communications, innovation and policy interactions in Lower Saxony's Network for Renewable Resources (3N) in Germany. This consortium will deliver six interconnected research outputs: 1. The establishment of a new S. viminalis population comprising accessions of potential value across Europe from existing unique germplasm collections held by partners; 2. The deployment of association mapping methodologies to willow for the first time; 3. Building on and sharing existing research to identify candidate genes and polymorphic markers within the population; 4. Testing candidate genes and their alleles for associations with key productivity traits under a range on environments; 5. The analyse of existing public research outputs for relevance to the genetic improvement of willow across Europe; 6. The proactive engagement of key stakeholders, including the ERANET's funding authorities, to ensure delivery into practice so that the research provides a public legacy for efficient research in the future. In recent years, Swedish and UK breeding programmes, underpinned by molecular approaches, have made significant progress in terms of improving willow SRC. As SRC willow production increases across Europe, suitable cultivars for a range of contrasting environments will be required. This research will deliver understanding into breeding programmes (including partners' breeding programmes) about the genetic basis of yield in the context of different European environments. It will deploy association mapping methodologies in willow for the first time through which the measurable characteristics of genes in candidate clones are associated with clone performance in diverse environments. Phenotyping of the population across a range of contrasting European sites will be used to link beneficial traits to variation in genes and provide an understanding of yield in the context of diverse environments, including on marginal land and under conditions relevant to a warmed climate. The population and associated trait data will also provide a valuable, permanent resource for use within existing and future national research programmes enabling the efficiency and delivery of the ERANET's partners public research effort to be improved in the longer term.

短轮伐期矮林（SRC）杨柳（柳属）是温带地区最先进的第二代能源作物之一。通过英国和瑞典两个独立的领先计划领导的遗传和基因组方法的支持，这种作物的育种和改良得到了显着加强。为了进一步发展作物，需要在更广泛的环境中生长的品种，并且这些品种是未来气候的证明。这里提出的研究将增加公共研究的有效性，支持遗传改良的杨柳在欧洲短轮伐期矮林结合两个领先的努力，并针对这些目标。为此，它将采取共同的方法来开展关键的基础研究，开发和共享关键的研究和遗传资源，并与利益攸关方积极和集体地合作，将这项研究付诸实践。这项研究将欧洲领先的公共资助研究结合起来，该研究基于SRC杨柳遗传改良和公共育种方案，该方案位于英国的Rothamsted，瑞典农业科学大学和乌普萨拉的长期瑞典杨柳育种工作; Lantmännen/Agroenergi AB是欧洲首屈一指的杨柳私营部门营销商;以及德国下萨克森州可再生资源网络（3 N）在表型分析、科学交流、创新和政策互动方面的专业知识。该联盟将提供六个相互关联的研究成果：1。建立了新的S. viminalis种群，其包括来自合作伙伴持有的现有独特种质集合的在整个欧洲具有潜在价值的种质; 2.首次将关联映射方法部署到杨柳上; 3.建立和分享现有的研究，以确定候选基因和多态性标记的人口; 4。在一定的环境条件下检测候选基因及其等位基因与关键生产性状的关联性;分析现有的公共研究成果与整个欧洲杨柳遗传改良的相关性; 6.包括ERANET的供资当局在内的主要利益攸关方的积极参与，以确保将研究成果付诸实践，从而为今后的有效研究提供公共遗产。近年来，瑞典和英国的育种计划，分子方法的支持下，在改善杨柳SRC方面取得了重大进展。随着SRC杨柳生产在整个欧洲的增加，将需要一系列对比环境的合适品种。这项研究将使育种计划（包括合作伙伴的育种计划）了解欧洲不同环境下产量的遗传基础。它将首次在杨柳中部署关联映射方法，通过该方法，候选克隆中基因的可测量特征与不同环境中的克隆性能相关联。在一系列对比鲜明的欧洲地点的人口的表型将被用来链接有益的性状基因的变化，并提供在不同的环境，包括在边际土地和相关的气候变暖的条件下的产量的理解。人口和相关性状数据还将提供宝贵的永久资源，供现有和未来的国家研究方案使用，使ERANET合作伙伴的公共研究工作的效率和交付能够在较长时期内得到改善。
