Chinese research team builds completed broccoli DNA fingerprint map library

Reporters recently in Taizhou City, Zhejiang Province, held the 2019 Zhejiang Broccoli New Variety Conference was informed that in 2019, the National Broccoli good seed major scientific research joint research team completed the broccoli DNA fingerprint map library. Broccoli, also known as broccoli, is one of the world’s most important healthy vegetables, the broccoli industry has developed rapidly in China for more than 10 years. However, the supply of Chinese broccoli seeds has long been a foreign monopoly.

In 2018, the Ministry of Agriculture and Rural Affairs set up a national broccoli seed major scientific research joint research group, led by the Zhejiang Seed Management Station, Zhejiang Academy of Agricultural Sciences as the chief expert unit, the United Nations major broccoli scientific research and teaching units and seed enterprises a total of more than 20 joint research. The group aims to select and breed a number of new varieties of broccoli with significant prospects for promotion and application, which can partially replace foreign varieties or suitable for domestic consumption demand, and plans to achieve the goal of “alternative imports, leading the country and driving industries” within five years.

In 2019, the team will speed up the construction of the completion of China’s broccoli seed materials and the main breeding varieties OF DNA fingerprint map library, the establishment of “molecular identity card” as the focus of work, while the establishment of seed affinity and purity identification technology system, in order to promote the sharing of seed materials, and effectively protect independent intellectual property rights, accelerate the broccoli varieties” Localization” process. At the same time, in 2019, the group was bred into 51 new varieties, of which 31 applied for the protection of the right to breed.

It is understood that, as human fingerprints as identification, plant DNA fingerprint map for its labeled “molecular identity card”, can be used to regulate the seed market, to prevent the emergence of “same name or foreign body of the same name” phenomenon, in the variety intellectual property protection, seed purity inspection and other aspects have important application value.

“The completion of the construction and identification of the broccoli DNA fingerprint library will provide a strong technical guarantee for the sharing and distribution of benefits of broccoli seed resources, and ensure the protection of species rights and the sharing of seed materials.” Zhejiang Seed Management Station said.
