Six satellites such as Soybean Zhonghuang 13 and Zhonghuang 38 were satellites equipped with Satellite No. 7 in practice. The satellites were operated in space for 16 days. Soybean seeds were exposed to space radiation, space microgravity and space environment, , Resistance and yield have some variation, by selecting has been bred in the 103 soybean lines, in Liaoning Province, regional trials and production tests, excellent performance, has passed the Liaoning province variety validation, named Zhonghuang 73, which is China’s use of space breeding bred the first soybean varieties.
