On may 18th, the yunnan news service (journalist zhao jin lee hee-pil), the country's first-ever yunnan winter cherry seed was planted at a base of man's red gardens ltd. In warning county, yuk creek, yunnan province, marking a crucial step in yunnan winter cherry seeding。

On september 27, 2024, 220 grams (1,800) of yunnan winter cherry seeds, carefully selected by yunnan's red gardens ltd., carried on board china's first reusable re-entry technology test satellite - - on 11 october of the same year, the satellite 19 was launched from the liquor spring satellite launch centre by the long march 2 ting carrier rocket。
Journalists saw at the planting scene that, despite the drizzling rain, the enthusiasm of the seeders had not been affected at all. They will carefully plant in their packagings a grain of saturated seeds that has brought fresh changes to our cherry industry。

The seeds, which are scientifically conserved, can decipher the soil for about half a month, can be replanted at a height of about 1 metre and are expected to bloom in three years。
It is known that, by 2024, more than 600,000 acres had been cultivated and that more than 200 new varieties of cherry blossoms had been authorized throughout the country, but less than 10 per cent of them had a truly significant outreach value。
Space breeding is an innovative breeding method that induces genetic mutation of seeds through extreme space-specific environments such as microgravity, high radiation and ultra-low temperatures. Compared to traditional breeding techniques, space breeds have a significant advantage, such as high variability and short breeding cycles, and are able to generate excellent seed resources in a relatively short period of time. However, there is a great deal of randomity and uncontrollability in space breeding, so ground-based breeding is crucial。

Yunnan is one of the most resourceful areas of our country. Yunnan winter cherry blossoms, also known as yunnan sun-sakuri, are the only yunnan species that have seen cherry blossoms blooming in the winter and have become an important tree species in winter and early spring thanks to their high value. Yunnan winter cherry blossoms are of great significance for breeding in space, and they play a vital role in innovating the quality resources of cherry blossoms, enriching the country's cherry blossom species and facilitating the process of domestication of the cherry industry。
Professor guan wenling of yunnan university of agriculture stated at the seeding site that he would conduct an in-depth study of variant strains, using morphology, cytology, biochemical testing and molecular biology, to determine their suitable areas and environment for planting and to provide a scientific basis for large-scale growth and expansion。
The head of the base of yunnan's red horticulture company ltd. Also indicated that it would work closely with the yunnan agricultural university, the project participants, to keep a full track of the seed growing process and complete a series of rigorous scientific tests, such as stabilization observations, evaluation comparisons, from which new varieties of a more superior type such as colour, flower, flowering, resistance etc. Would be screened。
It was described that yunnan's red gardens ltd., which worked on the collection of cherry seed resources, the selection of new varieties, and the cultivation and extension of high-quality trees, had been successful in obtaining four national-level authorizations for new cherry varieties and eight provincial registrations for new cherry varieties。
