The project aims to understand genetic and environmental factors that limit how fast genomic combinations can be generated by modifying the recombination rates between chromosomes. Plant breeding is based around genetic diversity, but modern breeding programs have captured only a small proportion of the variation available in wild relatives and land races. Knowledge of diversity in this wild germplasm pool is increasing and the challenge is to quickly and efficiently introduce this variation into elite lines. This project’s findings are expected to transform wheat and barley breeding methods by unlocking the genetic diversity to produce new varieties. This will enhance and protect a critical and valuable rural industry.

该项目旨在了解遗传和环境因素，这些因素限制了通过改变染色体之间的重组率来产生基因组组合的速度。植物育种是基于遗传多样性，但现代育种计划只捕获了野生近缘种和陆生种中的一小部分变异。对该野生种质库的多样性的了解正在增加，挑战是快速有效地将这种变异引入到优良品系中。该项目的研究结果有望通过释放遗传多样性来生产新品种，从而改变小麦和大麦的育种方法。这将加强和保护一个重要和宝贵的农村工业。
