This innovative project will provide the critical first step in a project that will provide UK farmers with a much-needed profitable break crop alternative to OSR and help to reduce dependence on imported soya. Arable farmers urgently need technology that reduces inputs, reduces disease and enables a better profit. As a nitrogen-fixing break crop with excellent protein content, lupins could enhance agriculture at a global scale. However, as a relatively newly domesticated species, an intensive breeding programme is needed to optimise varieties for a range of environments. This project will assess white lupins (_L. albus_) in the UK to identify genetic material with traits useful for a subsequent breeding programme focused on developing varieties better suited to UK and temperate conditions. The core innovation comes from previous work on genetic analysis of _L. albus_ that will enable introduction of novel germplasm and rapid recovery of the elite germplasm traits, most notably low alkaloid content. Wild lupins have high alkaloid content making them bitter and unpalatable. Current breeding programmes of _L. albus_ have been limited to a relatively narrow range of germplasm, all descended from a single source, in order to maintain low-alkaloids in the crop. As a result, much of the diversity of the domesticated portion of the species, and the potentially useful traits contained within, has been under-utilised. Now, with our unique knowledge of _L. albus_ genetics, this diversity can be integrated into a marker assisted breeding programme focused on improving lupins for UK and temperate agriculture. This project will conduct the initial field trials of a wide range of _L. albus_ material to assess and identify the most useful lines for the subsequent breeding programme. The early stage project will enhance the knowhow of Secure Harvests Ltd. (the applicant company, a UK SME), leveraging private investment in a large scale breeding programme. As such benefits to both SHL and the UK economy are expected, making this project excellent value for money for both the company and the public purse.

这一创新项目将为一个项目迈出关键的第一步，该项目将为英国农民提供急需的有利可图的间歇作物替代OSR，并有助于减少对进口大豆的依赖。可耕地农民迫切需要减少投入、减少疾病和提高利润的技术。羽扇豆作为一种蛋白质含量高的固氮作物，可以在全球范围内促进农业发展。然而，作为一个相对较新的驯化物种，需要一个密集的育种计划，以优化品种的范围内的环境。本项目将评估白色羽扇豆（_L。albus_），以鉴定具有对随后的育种计划有用的性状的遗传材料，该育种计划的重点是开发更适合英国和温带条件的品种。本论文的核心创新点来自于前人对L.这将能够引进新的种质和快速恢复优良种质性状，最显著的是低生物碱含量。野生羽扇豆具有高生物碱含量，使其苦味和不适口。目前的育种计划_L。albus_仅限于相对狭窄范围的种质，所有种质都来自单一来源，以保持作物中的低生物碱。因此，物种驯化部分的大部分多样性以及其中包含的潜在有用特征都没有得到充分利用。现在，凭借我们对_L的独特知识。albus_ genetics，这种多样性可以整合到一个标记辅助育种计划，重点是改善羽扇豆为英国和温带农业。该项目将进行大范围的初步田间试验。albus_ material，以评估和确定对随后的育种计划最有用的品系。早期项目将提高Secure Harvests Ltd.（申请公司，一家英国中小企业）的专业知识，利用私人投资进行大规模育种计划。因此，SHL和英国经济都有望从中受益，使该项目对公司和公共资金都具有很好的价值。
