糜子(Panicum miliaceum L.)是世界农业史上最早驯化的作物，生长周期短、水分利用效率高。关于糜子的地理起源存在中国北方起源论和东欧起源学说。中国北方起源论目前已经获得了一些考古学和遗传学证据的支持，而东欧起源学说尚存争议。本研究拟采用全基因组重测序技术鉴定糜子基因组水平上的遗传变异情况，结合品种来源地和文献记载研究糜子的群体结构和遗传多样性特点，探讨糜子的起源和演化情况，为理解糜子的驯化和传播提供基因组水平的依据。

Broomcorn millet (Panicum miliaceum L.) was the earliest domesticated crop worldwide with short growth period and high water use efficiency. There were two theories concerning the geographical origin of broomcorn millet, northern China and eastern Europe. The northern China theory was supported by a set of archeological and genetical evidence, while the eastern Europe theory was controversial. In this study, we will detect the genome-wide variants of broomcorn millet using the whole-genome resequencing technology. We will further study the population structure and genetic diversity patterns in combining with the source location of accessions and records in the literature. We will also explore the origin and evolution of domesticated broomcorn millet. Overall, this study will provide genome-level evidence for the understanding of the domestication and dissemination of broomcorn millet.
