A new tremella strain, HT108, has been officially recognized as Fujian province's pioneering space breeding edible fungus variety. Developed in Gutian county, Ningde city, this achievement represents a significant milestone in edible fungi space breeding technology in the region.

Researchers developed HT108 from the initial strain of Gutian Tremella Tr21, Fujian's primary tremella variety. HT108 was launched into space aboard the Shenzhou-16 manned spacecraft on May 30, 2023. After undergoing a 15-day space-induced mutation, the strain returned to Earth. Nearly two years of rigorous selection and cultivation experiments confirmed HT108 stable genetic traits.

This innovative strain excels in three key aspects: it features remarkable commercial attributes with a golden-yellow hue and a rounded, compact shape; it boasts exceptional nutritional quality, with significant increases of 60 percent in total flavones, 55.6 percent in total polyphenols, and 13.7 percent in crude polysaccharides compared to control varieties; and it showcases stable production performance, yielding over 12 percent more than traditional varieties.

Gutian county, known as China's "capital of edible fungi", achieved a total industry value of 28 billion yuan ($3.86 billion) last year, with tremella production dominating over 85 percent of the global market.

This success in space seed breeding is set to drive the industry towards high-end and branded advancements, aiding in the establishment of a billion-dollar industry cluster for "Gutian tremella". The county has already established the nation's first edible fungus space breeding laboratory and aims to establish three to five additional space strains within the next three years.
