The invention provides a potato StDWF1 gene and a preparation method thereof and a method for overexpressing the same to promote rapid rooting of potatoes, and relates to the field of potato molecularbiology. Through StDWF1 gene cloning, overexpression vector construction, agrobacterium impregnation and other following steps, the purpose of overexpressing the potato StDWF1 gene to promote rapid rooting of the potatoes is achieved; rooting is advanced by at least 10 days, so that enhancement on the growth trend of potato plants is facilitated. 本发明提供种马铃薯StDWF1基因及其制备方法以及过表达该基因以促进马铃薯快速生根的方法，涉及马铃薯分子生物学领域，通过StDWF1基因克隆、过表达载体构建、农杆菌浸染转入等步骤实现通过过表达马铃薯StDWF1基因促进马铃薯快速生根的目的，至少提前10天生根，有利于增强马铃薯植株生长长势。
