Wheat yield gains have averaged an annualized 1.14% increase worldwide from 1991 to 2012. However, considering FAO projections that indicate the world population will exceed 9 billion in 2050, this incremental development in a basic foodstuff needs to improve dramatically. As part of the effort to improve wheat yields the International Wheat Yield Partnership has the goal of increasing wheat yields by 50% in the next 20 years. Two key protagonists in this global wheat breeding effort are Canada and the UK where research institutions are working to achieve this goal.It is recognised that this will require not only the development of new ideas and innovative approaches to discover new alleles and traits that underlie yield gains, but also dedicated breeding efforts to incorporate the traits into elite genetic backgrounds. Yield gains are not realized until they are delivered as finished cultivars into the hands of growers. Wheat breeding programmes driven by traditional, phenotypic, selection accumulate favourable alleles and develop cultivars that result in high and stable yield in the given target environment. In wheat breeding, the necessity to develop cultivars with very specific end use quality targets increases the tendency to limit breeding work to elite-by-elite crossing, which consequently leads to a narrowing of the genetic background. Except for disease resistance alleles, which are often specifically targeted for the development of new cultivars, relatively little effort is typically incurred to broaden the genetic diversity of breeding programmes in order to discover under-utilized or novel alleles for agronomic performance and yield. This project proposes to share germplasm with a range of yield potentials and test cross diverse wheat growing environments.By sharing genetic improvements between diverse breeding programmes, a foundation for the delivery of increased wheat yield in the form of new spring and winter wheat cultivars can be laid. Improvements in wheat yields can provide considerable return on investment for wheat producers. For example, a 5% increase in Canadian wheat production would have a farm gate value of approximately $300 million dollars ($CDN) for the Canadian economy.

从1991年到2012年，全球小麦产量年均增长1.14%。然而，考虑到粮农组织的预测表明，到2050年世界人口将超过90亿，基本粮食的这种增量发展需要大幅改善。作为提高小麦产量努力的一部分，国际小麦产量伙伴关系的目标是在未来20年内将小麦产量提高50%。加拿大和英国是全球小麦育种工作的两个主要参与者，两国的研究机构正在努力实现这一目标。人们认识到，这不仅需要发展新的想法和创新的方法来发现新的等位基因和特性，从而提高产量，还需要专门的育种努力，将这些特性纳入精英遗传背景。直到它们作为成品品种交付到种植者手中，产量才会增加。在传统、表型选择的驱动下，小麦育种计划积累了有利的等位基因，并培育出在特定目标环境下高产稳定的品种。在小麦育种中，培育具有非常具体的最终用途质量目标的品种的必要性增加了将育种工作限制在精英对精英杂交的趋势，从而导致遗传背景的缩小。除了抗病等位基因（通常专门用于开发新品种）之外，通常很少努力扩大育种计划的遗传多样性，以发现农艺性能和产量方面未充分利用的或新的等位基因。本项目提出了具有一系列产量潜力的种质资源共享，并在不同的小麦生长环境中进行试验。通过在不同育种计划之间共享遗传改良，可以为以春小麦和冬小麦新品种的形式提高小麦产量奠定基础。小麦产量的提高可以为小麦生产者提供可观的投资回报。例如，加拿大小麦产量增加5%，将为加拿大经济带来约3亿美元（加元）的农场价值。
