The Ministry of agriculture and rural areas recently said that based on the previous revision of the approval standards for rice and corn varieties, the national approval standards for wheat, soybean, cotton and other varieties will be revised in due time. By appropriately raising the approval threshold, guide the cultivation of breakthrough varieties, and strengthen the intellectual property protection of the seed industry. It is reported that during the 13th Five Year Plan period, 16800 major crop varieties were approved nationwide, of which rice and corn accounted for 83%. The rapid increase of rice and maize varieties has solved the problem of "lack of varieties" in the market, but at the same time, new problems such as weak original innovation ability of varieties, low entry threshold for examination and approval, and many homogeneous varieties are becoming more and more prominent. In September this year, the National Crop Variety Approval Committee issued the revised national rice and corn variety approval standards, focusing on three aspects, including clarifying the requirements for variety DNA fingerprint differences, improving variety yield and disease resistance. The person in charge of the National Crop Variety Approval Committee said that after the revision, the yield indicators of high and stable yield varieties of corn and rice and green and high-quality varieties of rice were increased by 2 percentage points, and the yield indicators of special varieties such as green and high-quality varieties of corn, fresh food and silage were defined, which increased by more than 3% compared with the control varieties of the same type. At the same time, the disease types and identification contents of diseases and insect pests in main ecological areas are added to improve the requirements of existing disease resistance. Experts said that revising the approval standards for major crops, controlling variety approval and appropriately raising the approval threshold will play an important role in solving the problems of many varieties and serious homogenization. It is also conducive to stimulate original innovation and improve the level of variety breeding. It is an important content in strengthening the intellectual property protection of seed industry. In recent years, China's seed industry market has been continuously optimized and the problem of inferior seeds has been basically solved, but the problems of license infringement and substantially similar imitation seeds have become prominent. Since the beginning of this year, the Ministry of agriculture and rural areas has not only been based on solving the current prominent problems, but also sought to solve the institutional and institutional obstacles that lay the foundation and benefit the long-term. It has actively promoted its work from the four levels of legislation, judicature, law enforcement and technical standards, strengthened the protection of intellectual property rights and encouraged original innovation. These include promoting the revision of the seed law, establishing a substantive derivative variety system, extending the protection chain, increasing compensation, carrying out a three-year "national seed industry supervision and law enforcement year" and launching a six-month special rectification action for seed industry intellectual property protection. The Ministry of agriculture and rural areas also signed a memorandum of cooperation with the Supreme People's Court on strengthening the protection of intellectual property rights in the seed industry, cooperated with the Supreme People's court to study and issue judicial interpretations on specific application of legal issues in the trial of disputes over infringement of new plant variety rights, and strengthened judicial protection. The head of the National Crop Variety Approval Committee said that in the future, the national wheat, soybean and cotton variety approval standards will be revised in due time according to the needs of industrial development and variety innovation and on the basis of full investigation, research and listening to the opinions of all parties.
