Method for creating triticale new germplasm resources based on distant hybridization technology

The invention belongs to the technical field of wheat breeding, and discloses a method for creating triticale new germplasm resources based on a distant hybridization technology. The method comprises the steps that Polish wheat and common wheat are selected to hybridize to obtain a first generation F1 sterile line; the first generation F1 sterile line is hybridized with the common wheat to obtain a second generation F1 sterile line; the second generation F1 sterile line is hybridized with the common wheat to obtain a third generation F1 sterile line; the second generation F1 sterile line is hybridized with hard-grained wheat to obtain a third generation F1 sterile line; and the third generation F1 sterile line is hybridized with triticale, the fourth generation F1 sterile line is divided into fertility and sterility, the next generation of seeds is harvested in a mixed mode, the F2 generation has a sterile line and further has a fertile triticale selective line, and new germplasm resources are bred through sy
