Potato seeds that embarked on a space journey aboard the Shenzhou 14 spacecraft have now been successfully cultivated and harvested after extensive research and planting efforts. Learn about the implications and future prospects of this innovative endeavor.
In December of last year, 20,000 potato seeds were transported on the Shenzhou 14 spacecraft, traveling through space for 182 days before returning to Earth. These seeds were then entrusted to the National Potato Engineering Technology Research Center in Lao Ling, Dezhou, for scientific study and cultivation. Today, after nearly half a year of dedicated research and planting by scientific researchers, the first batch of “space potatoes” has been harvested.

The Xujia base of LaoLing Xisen Potato Industry Group, managed by Kong Haiming, has played a pivotal role in this endeavor. The potato plants, which have been growing for approximately 90 days, are now ready for harvest. While this initial harvest consists of miniature potatoes, referred to as C0-generation seed potatoes, further cultivation and selection will lead to the production of subsequent generations, such as C1, C2, C3, and so on.
The development of space potatoes holds great promise for the future. The Xisen Potato Industry Group, situated in Huangjia Town, Lao Ling City, Dezhou, has the capacity to produce 800 million miniature potato seeds each year. These virus-free seed potatoes can effectively support the planting needs of 2 million hectares of land. Equipped with advanced facilities including sterile seed potato detoxification, tissue culture workshops, an underground artificial intelligence climate room, a large constant temperature warehouse, and soilless cultivation aphid-proof greenhouses, the Xisen Group has made significant advancements in the field of potato cultivation.
Through extensive research and development, the Xisen Group has successfully introduced numerous new potato varieties with independent intellectual property rights. Notably, their varieties such as “Xisen No. 3,” “Xisen No. 4,” and “Xisen No. 5” have surpassed imported varieties in terms of quality and output. The group has cultivated a total of 18 new varieties, with 11 of them receiving variety approval and national registration.
Moreover, the Xisen Potato Industry Group actively collaborates with overseas universities and enterprises, facilitating the export of virus-free potato seedlings to countries like Kazakhstan. The successful promotion of the “Xisen 6” variety in Kazakhstan has further strengthened the cooperative ties between the two parties. Despite the challenges posed by the pandemic, the reopening of the market is expected to bring forth new developments and opportunities.
The cultivation of space potatoes marks a significant milestone in agricultural innovation. As further progress is made in optimizing yield, starch content, and resistance to environmental factors, these extraordinary tubers may eventually find their way onto consumers’ tables. While it may take several years of dedicated practice and refinement, the future of space potatoes holds tremendous potential for enhancing global food security and agricultural sustainability.
