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，全球平均每年增长了1.14％的小麦收益率。但是，考虑到2050年世界人口将超过90亿人口的粮农组织预测，基本食品中这种增量的发展需要大大改善。作为提高小麦产量的努力的一部分，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％。在这项全球小麦繁殖工作中的两个主要主角是加拿大和英国，研究机构正在努力实现这一目标。这不仅需要开发新的思想和创新方法，以发现基于增长的新等位基因和特征，而且还需要专门的繁殖努力，以将特征纳入Elite遗传背景。在将成品品种交付到种植者手中之前，不会实现收益率的收益。由传统，表型，选择驱动的小麦育种计划积累了有利的等位基因，并开发了在给定目标环境中产生高产量的品种。在小麦育种中，开发具有非常特殊最终使用质量目标的品种的必要性增加了将繁殖工作限制为精英穿越精英的趋势，从而导致遗传背景的变窄。除了抗病性等位基因（通常是针对新品种开发的疾病性等位基因）外，通常很少要努力扩大育种计划的遗传多样性，以发现未充分利用或新颖的等位基因以实现农艺性能和产量。该项目建议与一系列产量潜力共享种质，并测试跨多种小麦生长环境。通过在各种育种计划之间共享遗传改善，可以建立新春季和冬小麦品种形式增加小麦产量的基础。小麦产量的提高可以为小麦生产商提供可观的投资回报。例如，加拿大小麦的产量增加了5％的农场门价值约为3亿加元（$ CDN）。
