It introduces the progress on researches of space breeding both in USA and Russia who have processed the technique of space shuttle and in Germany，Canada，Australia，Brazil who can obtain the loading capacity of space shuttles. Overall，international space breeding is only a small branch of space biology，which presents a general picture that effects of space on biology are intensively studied and practice on space breeding are relatively less undertaken.
