The crop root systems are poorly suited to harsh conditions in Australian agriculture, especially as climate is getting drier. Poor water-use efficiency lowers crop yields below the potential yield; moreover, unutilised water and nutrients contribute to environmental problems, eg salinity and eutrophication. This project will use our simulation model to develop computer-aided design of 3-D root structure and function (water and nutrient uptake) tailored to particular environments. Modelling will also link suitable root traits to genetic markers in well-characterised lupin germplasm. The blueprint developed here will be adaptable to other crops. The project will enhance breeding for increased water- and nutrient-use efficiency.

作物根系不太适合澳大利亚农业的恶劣条件，尤其是在气候越来越干燥的情况下。水分利用效率低下使作物产量低于潜在产量；此外，未利用的水和养分会造成环境问题，例如盐度和富营养化。这个项目将使用我们的模拟模型来开发针对特定环境的三维根系结构和功能（水和养分吸收）的计算机辅助设计。建模还将把适当的根性状与特征良好的卢平种质的遗传标记联系起来。这里开发的蓝图将适用于其他作物。该项目将加强养殖，提高水和养分的利用效率。
