In August of 2022, over 8,000 flower seeds arrived at Yunnan Jinke Flower Engineering Research Center Co., Ltd. after their spaceflight trip aboard Shenzhou manned spaceship.
Space breeding refers to exposing seeds or strains to cosmic radiation and microgravity in space to mutate their genes, so as to create new species or varieties with greater performances like shorter growth periods, higher yield and better resistance to diseases.
According to Tian Liantong, a technologist of Jinke Flower Engineering Research Center Co., Ltd., usually it takes five years to breed new flower species which consumers could buy on market, and some species even need ten years to go through the process from breeding to becoming commodity, as they have to pass various and harsh growth conditions including temperature, humidity and nutrition supply.
In recent years, local government of Yunnan and scientific research institutions as well as enterprises have been making great efforts, space breeding included, in cultivating new flower species to enrich flowers supply. By the end of 2022, over 950 new flower species have been independently fostered within Yunnan and over 1,000 introduced new flower species have been recorded. (Xinhua/Hu Chao)
