Abstract: Mechanization of field experiments is the only way to improve crop breeding and seed propagation effects. It can not only improve the efficiency of field trials, save investment, shorten the breeding cycle, but also provide a better technology and equipment for the breeding of new varieties and propagation. In order to improve the breeding of field tests of the operating efficiency of machinery and precision, to the breeders and seed base to provide the best machinery, equipment and apparatus, in the joint efforts of international breeders, agronomists and mechanical scientists, the International Association on Mechanization of Field Experiments (IAMFE) was established in 1964. At the beginning of this paper, a brief introduction of the history of the IAMFE and the China Branch was given. Then the fields engaged was described, the scope of the study, the achievements and the international development of IAMFE were discussed in detail. Finally, a prospect of the development of the IAMFE was given.
