Abstract:

The development and utilization of space resources has been a new research field with keen worldwide competition. Space provides a special environment with supervacuum, microgravity and strong cosmic radiation. Good achievements have been made by space induced mutations for crop improvement, especially in rice, wheat, cotton, sweet pepper, tomato and sesame, with some very useful rare mutants which might make a great breakthrough in crop yield and quality improvement, the current status of space botany research in aboard was briefly introduced. The research progress and perspedives of application of space technology for crop improvement by using recoverable satellite techniques in China have been reviewed.

Key words: crop, space mutagenesis;space breeding, new cultivar
