The conclusion of the study on the origin of Chinese cultivation and wild sea belt groups.

The seaweed species bank research team of the Institute of Oceanographic Research of the Chinese Academy of Sciences, in cooperation with Yotsukura, a professor at Hokkaido University in Japan, conducted the first retrospective study of Chinese cultivation and wild sea belt groups, which initially confirmed that The seaweed populations in China originated in Hokkaido, Japan. Using high polymorphic microsatellite (SSR) markers, the
research team compared the representative natural groups of china's representative sea-belt groups (cultivation and natural groups), Russia, Korea and Hokkaido, Japan, and found that the parameters such as allephal number, private allephic gene number and hybridity of Chinese populations were significantly lower than those of Japanese groups.
compared with other groups, the genetic distance between the manic zone groups in China and the Japanese population is the closest, showing a clear founder effect.
in China's economic seaweed, the cultivation history, scale, yield and impact on social economy have the first place.
2016, China's total production of manic belt reached 1.4 million tons (dry goods).
Regarding the origin of China's manoe belt, the now generally accepted view is: "The manoeor is not an indigenous species of our country, it was introduced in 1927 from Hakodial in Hokkaido, Japan, to Dalian, China, and gradually spread to Yantai, Qingdao and other places."
" has always lacked conclusive experimental biological evidence, and the research results provide a scientific basis for the study of the origin of the sea belt in China.
the paper, published in the Journal of Applied Algae, was first published by Associate Researcher Monophysics.
At the same time, the scientific research team also used SSR mark to carry out a systematic molecular genetic analysis of the main cultivated varieties (departments) of the northern sea belt in China, revealing from the molecular level that there are irregular use of names, blurred variety boundaries, varieties mixed and so on in the mainstream sea belt varieties in the northern region of China, which provide important reference information for the future development direction of the industrialization of the good sea belt species.
the study was published in the journal AlgaeOlogy Research, and the first author was Li Xia, a research assistant.
