The project’s goal is to improve crop breeding for increased efficiency of acquiring soil resources. Increasing a crop’s efficiency in capturing soil resources (water and nutrients) is an imperative task in ensuring food security. This project plans to use barley as the model cereal crop and characterise root traits in a panel of cultivars assembled to represent maximum diversity as well as in biparental mapping population followed by association and linkage mapping to identify genetic markers linked with specific root traits. These markers will be incorporated into a computer model of 3-D root structure and function. The enhanced computer model would be able to simulate optimal root systems for specific environments and generate a list of selectable root-trait markers.

该项目的目标是改进作物育种，提高获取土壤资源的效率，这是确保粮食安全的一项紧迫任务。表征一组代表最大多样性的品种以及双亲作图群体中的根性状，然后进行关联和连锁作图，以识别与特定根性状相关的遗传标记。这些标记将被纳入 3D 根的计算机模型中。结构和增强的计算机模型将能够模拟特定环境的最佳根系并生成可选择的根性状标记列表。
