[Explanation] On August 23, the fresh cut flower seeds that had traveled in space for more than 3 months on the Shenzhou 12 manned spacecraft officially arrived at Yunnan Jinke Flower Engineering Research Center Co., Ltd. located in Shilin County, Kunming City, Yunnan Province.
[Explanation] The researchers will sterilize the seeds, refrigerate (90 days), germinate, and sow a series of processes, and finally form seedlings and cultivate "roses from stars".
[Explanation] Space breeding is also known as "space mutation breeding". Under the influence of the space environment, the genetic arrangement or genetic structure of seeds may mutate.
[Explanation] The flower seeds that flew into space with the Shenzhou 12 manned spacecraft are the spaceborne breeding jointly selected by the National Flower Engineering Technology Center, the National Flower Industry Technology Innovation Alliance, and Yunnan Jinke Flower Engineering Research Center Co., Ltd. It is composed of 21 kinds of rose hybrid seeds in three series of edible, garden and cut flowers, with a total weight of 101.8 grams.

Certainly the more exotic the flowers are, the more we hope to get them.
For example, some shapes, like a floral scent type.
If we say that after this mutagenesis, because we have some varieties that are selected from scented varieties, such as "lychee" and "white lychee", these varieties are formed from the female parent, then it will come out with a stronger fragrance. We also Must be very happy.
[Explanation] He Qiong said that each "space seed" may become a new variety, and the flower shape and color may appear completely different.
The base will select and breed seedlings with positive mutation traits for the cultivation and application of new varieties.
It is expected that the stable new varieties will be officially launched on the market after four years.
At that time, Kunming Flower Auction Center will take advantage of big data and platform to publicize and promote the new roses of "Space Seeds".
[Explanation] The benefits brought by aerospace breeding are very large. New varieties that can successfully pass aerospace breeding generally have the advantages of high yield, high quality, and strong disease resistance.
The seed industry is regarded as the "chip" of agriculture, and new varieties are the internal driving force for the sustainable, healthy and high-quality development of the flower industry.
[Concurrent] He Qiong, Executive Deputy General Manager of Yunnan Jinke Flower Engineering Research Center Co., Ltd.
The space breeding this time is a supplement to our cross-breeding process. In fact, it has also been expanded. Then in our next step, we will also build our roses (variety) into a rose library, a world of roses, A data center, integration center in Rose.
[Explanation] It is reported that this "Space Seed" is a new step in the research and development of new flower varieties in addition to hybrid breeding and other methods. It is of great significance for cultivating excellent new products and strengthening the research and development of new flowers with independent intellectual property rights.
