Using gene transferring technology on maize for genetic improvement, to nurture the maize varieties of different characters with special quality and different uses, that provides an effective new way for solve the many problems of maize production, and has shown great power and potential. The transformation mechanism of the pollen tube pathway method and its application in gene engineering improvement of maize inbred lines were summarized in this paper, meanwhile, the advantages and the shortages in the gene engineering were simply introduced. The prospects of this method were also discussed．
