The Chinese research team built and completed the xilan's DNA fingerprint map library

xinhua News Agency, Hangzhou, January 11 (Reporter Xu Yanda, Fang Qxuan) reporter recently held in Taizhou City, Zhejiang Province, the 2019 Zhejiang Xilanhua New Variety Conference was informed that in 2019, the national xilanhua good species of major scientific research joint research team completed the completion of the xilanhua DNA fingerprint map library.
, also known as cauliflower, is one of the most important healthy vegetables in the world, and the orchid industry has developed rapidly in China for more than 10 years. However, the supply of chinese orchid seeds has long been a foreign monopoly.
In 2018, the Ministry of Agriculture and Rural Affairs established the National Joint Research Group on The Good Seeds of Western Orchids, led by the Seed Management Station of Zhejiang Province, with Zhejiang Agriculture
as the chief expert unit, and more than 20 major orchid scientific research and teaching units and seed enterprises in the United Nations carrying out joint research and research. The aim of the research group is to select and breed a number of new varieties of orchids with significant promotion and application prospects, which can partially replace foreign varieties or suitable for domestic consumption demand, and plans to achieve the goal of "alternative imports, leading the whole country and driving the industry" within 5 years.
2019, the team will speed up the construction of the completion of China's xilan flower species materials and the main breeding varieties DNA fingerprint map library, the establishment of "molecular identity card" as the focus of work, while the establishment of species kinship and purity identification technology system, in order to promote the sharing of species materials, and effectively protect independent intellectual property rights, accelerate the "localization" process of western orchid varieties. At the same time, in 2019, the research group into 51 new varieties, of which 31 applied for the protection of the right to varieties.
It is understood that, as human fingerprints as identity, the DNA fingerprint map of plants for its "molecular identity card", can be used to regulate the seed market, to prevent the emergence of "same name or foreign name" phenomenon, in the variety of intellectual property protection, seed purity testing and other aspects have important application value.
" the completion of the construction of the XIA DNA fingerprint map library and the establishment of the identification technology system, will be to achieve the sharing of xilan flower species resources and benefit distribution to provide a strong technical guarantee for the protection of species rights and the sharing of species materials to protect the common escort. Zhejiang Seed Management Station said.
