Gf Securities Co., Ltd. has released a research report highlighting that China's seed industry has long faced issues with imitative breeding and variety homogeneity. The implementation of the Essentially Derived Variety (EDV) system, through mandatory licensing and profit-sharing arrangements (with distribution ratios negotiated between parties and industry associations encouraged to set benchmarks), significantly raises the cost of superficial rebranding in breeding, directing resources toward original innovation. For seed companies, leading firms with core germplasm resources, breakthrough self-bred varieties, and sustained R&D capabilities will see a systematic boost in the value and bargaining power of their variety rights. Small and medium-sized enterprises reliant on cosmetic modifications and homogeneous competition face pressure to exit, potentially increasing industry concentration. Currently, self-bred varieties account for over 95% of China's crop area, and the EDV system's rollout, combined with green channel reviews for variety approval and crackdowns on counterfeit seeds, is expected to accelerate variety renewal.
Gf Securities outlines key points: On July 27, the Ministry of Agriculture and Rural Affairs issued Announcement No. 1034, unveiling the "Catalogue for the Implementation of the Agricultural Plant Essentially Derived Variety System (First Batch)," which includes 10 crops—rice, wheat, cotton, rapeseed, peanut, Chinese cabbage, chili, foxtail millet, fava bean, and peach—under the EDV system. It also released accompanying guidelines for determination, thresholds, appraisal institution conditions, and established an expert database.
After five years from legislation to implementation, the EDV system has finally been realized, completing China's seed industry intellectual property protection framework. The EDV system, rooted in the 1991 Act of the UPOV Convention, stipulates that derived varieties resulting from simple cosmetic modifications of authorized varieties, though eligible for independent variety rights, require permission from and profit-sharing with the original right holder for commercial use, including production, reproduction, sale, and import/export. The revised Seed Law in December 2021 first established the EDV system (effective March 1, 2022), authorizing the State Council to set implementation steps and methods. The 2025 revision of the "Regulations on the Protection of New Plant Varieties" (effective June 1, 2025) further clarifies a phased rollout via a catalogue system. The accompanying guidelines specify that EDV determination primarily relies on molecular testing (prioritizing high-throughput technologies like SNP and MNP), setting genetic similarity thresholds per crop. For rice, wheat, cotton, foxtail millet, peanut, and chili, the threshold is set at 90%, while for rapeseed, fava bean, and peach, it is 85%. Reaching the threshold triggers EDV classification and a shift in the burden of proof.
The first batch excludes corn, with pilot crops "rolled out in phases," and subsequent expansion is worth monitoring. According to a Ministry of Agriculture press conference, catalogue crop selection was based on three factors: first, urgent industry demand—by end of 2025, applications for the 10 crops totaled 38,600, accounting for 35.5% of all agricultural plant variety applications; second, rich genetic diversity, with China's long-term preserved germplasm resources exceeding 220,000 accessions, ranking globally for each crop; third, mature identification technology, with DNA molecular testing and field phenotype identification standards for the 10 crops already published and widely used. Other crops will be evaluated and incorporated over time, ensuring orderly progress. Corn was not included in the first batch, but the Ministry of Agriculture had already initiated EDV system trials in 2023 within national rice, wheat, corn, and soybean breeding joint efforts. Corn is expected to be gradually included in subsequent batches.
Risk warnings include policy risks, natural disaster risks, and seed industry R&D progress falling short of expectations.
