Introducing genetic diversity from wild species into elite lines of wheat and barley may increase their resistance to the stresses they are exposed to in the field. Modern breeding cultivars could capture up to ten times more genetic variation. This project aims to gain fundamental insights into the genetic and environmental factors that limit the rates at which new genomic combinations can be made. This will transform wheat and barley breeding methods, unlocking available genetic diversity to produce new varieties.

将野生物种的遗传多样性引入小麦和大麦的优良品系中，可能会增加它们对田间胁迫的抵抗力。现代育种品种可以捕获多达十倍的遗传变异。该项目旨在从根本上了解限制新基因组组合速度的遗传和环境因素。这将改变小麦和大麦的育种方法，释放可用的遗传多样性，以生产新品种。
