Disclosed in the present invention is a method for creating dwarf winter wheat germplasm resources. The process comprises: screening high-quality parents for hybridization, performing anther tissue culturing, chromosome doubling and transplantation on an F1 generation, and screening the morphological indicators, cold resistance, physiological indicators and economic indicators of the offsprings according to standards until offsprings complying with the dwarf traits, equivalent to the dwarf winter wheat germplasm resources, are obtained. The method is simple and convenient to operate, can be used for creating a new excellent dwarf winter wheat germplasm, and provides a simple and effective breeding method for wheat breeders.
