Sweet potato is a vital staple food worldwide, particularly for small-scale farmers in drought-prone areas of the developing world, with Vitamin A-rich varieties proving an invaluable tool in combatting malnutrition. This project aims to resolve outstanding questions about the route to polyploidy, role of gene-flow, and development of edible storage roots in the origin and evolution of the sweet potato. Doing so will generate a comprehensive account of the evolutionary history and contemporary diversity of one of the world's most important crops and its closest relatives, and will also provide wider insights into the role of polyploidy and introgression in the processes of evolutionary adaptation and crop domestication. Such insights are of potential use in sustainably enhancing agricultural production by facilitating the incorporation of beneficial traits from crop wild relatives to promote Global Food Security and adaptation to environmental change.

甘薯是世界范围内的重要主食，特别是对发展中国家干旱易发地区的小规模农民来说，富含维生素A的品种被证明是对抗营养不良的宝贵工具。该项目旨在解决甘薯起源和进化中多倍体途径、基因流的作用和可食用贮藏根的发育等悬而未决的问题。这样做将产生一个世界上最重要的作物之一及其近亲的进化历史和当代多样性的全面说明，也将提供更广泛的了解多倍体和基因渗入在进化适应和作物驯化过程中的作用。这些见解在可持续地提高农业生产方面具有潜在的用途，可以促进作物野生亲缘植物的有益性状的结合，以促进全球粮食安全和适应环境变化。
