The Institute of Oceanology, Chinese Academy of Sciences has cultivated a new high-yield and high-quality hybrid kelp variety

Qingdao BEIJING, September 7 (Reporter Huyao Jie) China Kexue Yuan Institute of Oceans 7 news release, recently released by the Ministry of Agriculture and Rural new varieties of aquatic adopted in 2021 validation by China Kexue Yuan Institute of Marine seaweed genebank The high-yield and high-quality hybrid kelp "Zhongbao No.
1" jointly bred by the team and Dalian Haibao Fishery Co.
, Ltd.
is on the list
.

At present, during the growth process of China's kelp, there is a production method in which seedling manufacturers use a small number of parents to cultivate a large number of seedlings.
This has led to lower and lower genetic diversity of cultivated populations of different varieties, and the excellent cultivation and agronomic traits of the offspring are gradually lost, mainly as kelp.
The content of adult alginate decreased significantly, the algae became brittle, the dry kelp became yellow and stratified, the degeneration of false roots caused vegetable removal and yield decline, and the formation of sporangia earlier and earlier, affecting the quality of processed products

China Kexue Yuan Institute of Oceanography seaweed genebank team since 2008 in cooperation with the Dalian Co.
, Ltd.
to carry out sea-kelp fishery conservation of germplasm collection and breeding work
.

According to reports, "Zhongbao No.
1" has the remarkable advantages of high yield, wide algae, dark green color for hot vegetable processing, high yield, and no sporangia during the cultivation period.
Under the same cultivation conditions in the northern region, it is more Compared with cultured kelp, the average output in mid-to-late July increased by 63.
9%, and the hot vegetable processing yield increased by more than 10%.
It is suitable for cultivation in artificially controllable seawater bodies in coastal areas such as Liaoning and Shandong, and is deeply loved by kelp breeding companies

Kelp was introduced to China from Japan in 1927 and is an alien species
