“Shijian-8” is the first recoverable satellite for breeding purpose，which was launched in September 2006. It carried 9 categories and 2020 sets of biomaterials. After recovery，the breeding process was initiated immediately. A series of achievements have been made in the areas of space mutagenesis mechanism，development of new mutant germplasm and breeding of new mutant varieties. According to incomplete statistics，by 2020，methods for screening of space induced mutants have been established，elite mutants have been developed in crops such as wheat，rice，corn，and more than 50 new mutant varieties have been bred and planted by farmers. Over 160 peer-reviewed papers have been published in journals，more than 100 master’s and doctoral students have been trained. The progenies induced by spaceflight from “Shijian-8” will continue to play important roles in the study of space mutagen mechanism and development of new mutant varieties in crops.
