Wheat is the most important staple crop grown in the UK, and one of the two major crops grown in India. Nitrogen fertiliser is a key determinant of yield and the major cost of wheat production in both countries and excessive application can result in pollution of groundwater and increased production of greenhouse gases. Breeders and farmers in the UK and India have worked hard to improve the efficiency of use of applied nitrogen, by improving the uptake and utilization efficiency within the crop through genetic improvement, together with the precision of fertilizer application in the field. However, further improvements are required to face the challenges of increasing crop production for an expanding global population with increasing uncertainty of climate. Both yield and quality attributes are dependent upon nitrogen inputs and need to be incorporated into economic and sustainable solutions. We will therefore bring together the major UK and Indian wheat researchers with programmes on wheat improvement to determine the genetic control of nitrogen use efficiency in wheat. These comprise scientists from five Universities and Institutes in the UK and from six in New Delhi, Haryana and the Punjab, which is the major wheat-producing area of India.The studies will focus on comparisons of wheat lines and populations which differ in their nitrogen use efficiency. These lines will be grown in field experiments in both countries and studied in detail using a range of biochemical and molecular genetic approaches. This will lead to the identification of genes and molecular markers that can be exploited by wheat breeders globally, and to new strategies for improving the precision of nitrogen application which will delivered to farmers via well-established mechanisms in both countries. Furthermore, since similar mechanisms are expected to determine nitrogen use efficiency in other plant species the results should be of wider applicability to other crops and countries.In addition to supporting a closely integrated research programme in the UK and India, the Centre will also provide a legacy of shared facilities, technologies, genetic material and datasets that will facilitate longer term bilateral collaborations, and provide training in crop genetics and genomics and exchanges for early career scientists and students in both countries.

小麦是英国种植的最重要的主食作物，也是印度种植的两种主要作物之一。在这两个国家，氮肥是产量的关键决定因素，也是小麦生产的主要成本，过量施用会导致地下水污染和温室气体排放增加。英国和印度的育种家和农民一直在努力提高氮肥的利用效率，通过遗传改良提高作物的吸收和利用效率，同时提高田间施肥的精度。然而，在气候不确定性增加的情况下，全球人口不断增加，粮食产量不断增加，这一挑战需要进一步改进。产量和质量属性都取决于氮的投入，需要纳入经济和可持续的解决方案。因此，我们将联合英国和印度的主要小麦研究人员进行小麦改良项目，以确定小麦氮素利用效率的遗传控制。这些科学家包括来自英国五所大学和研究所的科学家，以及来自新德里、哈里亚纳邦和旁遮普邦的六所大学和研究所的科学家。旁遮普邦是印度主要的小麦产区。这些研究将侧重于比较氮素利用效率不同的小麦品系和群体。这些品系将在两国的田间试验中种植，并使用一系列生化和分子遗传学方法进行详细研究。这将导致全球小麦育种者可以利用的基因和分子标记的鉴定，以及提高氮施用精度的新策略，这些新策略将通过两国完善的机制交付给农民。此外，由于类似的机制有望确定其他植物物种的氮利用效率，其结果应更广泛地适用于其他作物和国家。除了支持英国和印度的一个紧密整合的研究项目外，该中心还将提供共享设施、技术、遗传物质和数据集的遗产，这将促进长期的双边合作，并为两国的早期职业科学家和学生提供作物遗传学和基因组学方面的培训和交流。
