Introduction
Plant Variety Testing Laboratory is a public welfare department specializing in DUS testing of plant varieties and seed quality assessment. It is responsible for the operation and maintenance of two platforms belonging to the Ministry of Agriculture and Rural Affairs, namely, the Tropical Crop Seed and Seedling Quality Supervision, Danzhou Sub-Center for DUS Testing of New Varieties of Plants.The research office has 29 members, including 2 part-time leaders and 16 auxiliary staff. Seven have advanced titles and three have doctorates.The honors included: Hainan High-level Talents (3 persons), National Advanced Individual of New Variety Protection (1 person), Hainan March Eighth Red Banner (1 person), and National DUS Test System Outstanding Youth (1 person).During the 13th Five-Year Plan period, we won the following honors: the title of National Advanced Collective for New Variety Protection of Plants from the Ministry of Agriculture and Rural Affairs, the first prize and the second prize of Technical Service Award from the Chinese Academy of Tropical Agricultural Sciences, and the title of advanced Collective for four consecutive years from 2017 to 2020.And during the 13th Five-Year Plan period, we received funding of 10.4 million yuan, issued 30 standards, published more than 20 papers, were authorized 6 patents, published 4 monographs, and completed nearly 4000 DUS tests and quality assessment tasks.
Research team
The laboratory director is Gao Ling, the deputy directors are Ying Dongshan and Liu Difa, the DUS test platform director is Researcher Liu Guodao, and the quality inspection platform director is researcher Wang Jiabao. The laboratory consists of three business sections, namely, plant variety DUS testing direction (person in charge: Liu Difa), seed quality testing direction (person in charge: Ying Dongshan), and research on new variety protection policy, quality control and information management (person in charge: Gao Ling).
Core objectives
Off-Season breeding crops and tropical crops as the research objects, the research team focuses on the theory, technology, model, standard and tool of testing, and builds an innovative R&D center of testing technology that connects with international standards and leads the application. In this process. We focused on the national and provincial intellectual property protection strategies and the development needs of off-Season breeding, based on the location and institutional advantages of Hainan Free Trade Port, and focused on the scientific problems of plant variety testing.We undertake plant varieties DUS test, VCU test, characteristics identification, seed and seedling quality testing, technical training and other work, to build a "one-stop" variety testing and identification comprehensive service center, and service seed industry intellectual property rights, plant varieties certification/registration/certification, etc.
Important research progress
Research Progress I: DUS testing technology and seed quality testing standards of plants in hot areas were systematically studied. DUS testing guidelines and technical regulations of 36 plant species and 39 seed (seedling) testing standards of agricultural and forestry plants were developed, and a standard system of tropical plant variety testing technology was constructed.
Research progress II: The evaluation and research of the standard variety of Passiflora were carried out, and the first standard variety nursery for tropical plant variety testing was constructed. Nearly 200 standard materials were preserved, which supported DUS testing and the revision of international UPOV testing guidelines for this variety.
Research progress III: The standard quality control system was developed for the reference of testing system. Under the support of normative technical system, we evaluated and identified nearly 4000 plant materials, providing basis for Chinese plant variety management. In the quality testing capability verification of the Ministry of Agriculture and Rural Affairs, the laboratory obtained good grade, ensuring the implementation of seed quality testing business.
