Genetic diversity underpins crop improvement but has become increasingly narrow in our major crops. Strategies exist for mobilising simple traits (e.g. disease resistance) from wild accessions or landraces into cultivars, but there are no effective approaches for introducing complex traits, including stress tolerance or components of yield. Using barley as an important crop and a genetic model, the project aims to address this problem by applying a novel approach; partial redomestication of wild accessions by introgressing genes required for modern farming, then evaluating the resulting partially adapted germplasm in hybrids with elite cultivars. The project expects to generate new and diverse germplasm pools for breeding.

遗传多样性是作物改良的基础，但在我们的主要作物中却变得越来越狭窄。存在将野生品种或地方品种的简单性状（例如抗病性）转化为栽培品种的策略，但还没有有效的方法来引入复杂性状，包括抗逆性或产量组成部分。利用大麦作为一种重要的作物和遗传模型，该项目旨在通过应用一种新的方法来解决这一问题;通过渗入现代农业所需的基因对野生种质进行部分再驯化，然后在与优良品种的杂交中评估所产生的部分适应种质。该项目预计将产生新的和多样化的育种种质库。
