This project assembles a world-class team of leaders in root research and wheat genetic improvement from seven institutes and five breeding companies, and brings this expertise into the IWYP programme. Our goal of optimising root systems is a critical component of the overarching IWYP aim of raising yield potential: higher yielding crops developed through IWYP will most likely demand more water and nutrients to support those yields, and roots must supply these in an efficient manner without draining any more carbon away from grain formation than is necessary to provide this function. The project builds on state-of-the-art developments in wheat genomic tools, germplasm resources, 'Speed Breeding', physiological and genetic understanding of root growth/development, high-throughput root phenotyping methods and the creation of novel genetic variation ready for exploitation. We establish a pipeline to validate the impact of root ideotype on yield, based on the use of: (1) recently cloned genes, (2) known QTL, and (3) de novo natural and artificial allele discovery. This pipeline provides staggered delivery of validated root ideotypes that will feed the breeding activities carried out by the IWYP Hub, participating breeding companies, and wider wheat breeding networks. By focusing on the often ignored 'invisible half' of the crop, this approach complements IWYP work on above ground traits, ultimately providing the knowledge and resources to allow above and below ground approaches to be combined in the future to maximise yield genetic gains.

该项目汇集了来自七个研究所和五个育种公司的世界级根系研究和小麦遗传改良领导者团队，并将这些专业知识带入IWYP计划。我们优化根系的目标是IWYP提高产量潜力的总体目标的关键组成部分：通过IWYP开发的高产作物很可能需要更多的水和养分来支持这些产量，而根系必须以有效的方式提供这些，而不会从谷物形成中排出比提供这一功能所需更多的碳。该项目建立在小麦基因组工具、种质资源、“快速育种”、对根系生长/发育的生理和遗传理解、高通量根系表型分析方法以及创造可供利用的新型遗传变异等方面的最新发展的基础上。我们建立了一个管道，以验证根理想型对产量的影响，基于使用：（1）最近克隆的基因，（2）已知的QTL，（3）从头自然和人工等位基因的发现。这条管道提供了交错交付的验证根理想型，将饲料由IWYP中心，参与育种公司和更广泛的小麦育种网络进行的育种活动。通过关注作物中经常被忽视的“看不见的那一半”，这种方法补充了IWYP在地上性状方面的工作，最终提供知识和资源，使地上和地下方法在未来结合起来，以最大限度地提高产量遗传增益。
