Aoxiangyu 819, Aoyu 966, and Aoyu 288 delivered yield gains of 6.0% to 8.6% over control varieties in two-year national regional trials; 30-day public notice period runs through November 22, 2026
Origin Agritech Limited (NASDAQ: SEED) ("Origin" or the "Company"), a leading Chinese agricultural technology company, today announced that three of its corn varieties, Aoxiangyu 819, Aoyu 966, and Aoyu 288, have passed the preliminary review of the 13th Session of the Fifth National Crop Variety Approval Committee of China. The three varieties are bred for the Huang-Huai-Hai Summer Corn Region, one of China's major corn-producing areas, and each outyielded its designated control variety in both the two-year national regional trials and the 2025 production trials.
The Committee published its preliminary review results on October 22, 2026, finding that the three varieties meet China's national standards for corn variety approval. Under China's Measures for the Approval of Major Crop Varieties, preliminary review is followed by a 30-day public notice period, which runs from October 22 through November 22, 2026. Following completion of the applicable approval procedures, the varieties are suitable for cultivation in major areas of the Huang-Huai-Hai Summer Corn Region, including parts of Henan, Shandong, Hebei, Shaanxi, Shanxi, Jiangsu, Anhui, and Hubei provinces.
Mr. Weibin Yan, Chief Executive Officer of Origin Agritech, commented: "The preliminary review of these three varieties is an important milestone for Origin's breeding and commercialization pipeline. Their consistent yield performance across regional and production trials demonstrates the strength of our breeding capabilities and provides additional products for our expansion in the Huang-Huai-Hai region."
"As we enter the Strong Growth Stage of our development plan, expanding our variety portfolio remains a key priority. Combined with our growing regional sales network and technology platform, these new varieties strengthen our foundation for sustainable growth and our long-term goal of becoming one of China's leading corn seed companies."
Yield Performance in National Trials
All three varieties demonstrated consistent yield advantages over the designated control varieties in China's national, regional, and production trials. One mu is one-fifteenth of a hectare, so a yield of 697.9 kilograms per mu equals roughly 10.5 metric tons per hectare, or about 167 bushels per acre.
Aoxiangyu 819, developed by Beijing Origin Agritech Seed Co., Ltd. and Hainan Aoyu Biotechnology Co., Ltd., achieved an average yield of 697.9 kilograms per mu over two years of regional trials, 8.6% above the control variety. In the 2025 production trial, Aoxiangyu 819 achieved an average yield of 662 kilograms per mu, 5.9% above the control.
Aoyu 966, also developed by Beijing Origin Agritech Seed Co., Ltd. and Hainan Aoyu Biotechnology Co., Ltd., achieved an average yield of 696.8 kilograms per mu over two years of regional trials, 6.9% above the control. In the 2025 production trial, the variety achieved an average yield of 668 kilograms per mu, 7.0% above the control.
Aoyu 288, developed by Beijing Origin Agritech Seed Co., Ltd., achieved an average yield of 670.2 kilograms per mu over two years of regional trials, 6.0% above the control. In its production trial, Aoyu 288 achieved an average yield of 694 kilograms per mu, 6.2% above the control.
The three varieties also demonstrated competitive agronomic characteristics, including maturity periods of approximately 103 days and 100-kernel weights ranging from 34.7 grams to 35.6 grams.
Expanding Origin's Commercial Variety Pipeline
The Huang-Huai-Hai region is a strategically important corn-growing area in China. The addition of three varieties with demonstrated yield advantages further expands Origin's product portfolio and provides additional opportunities to strengthen its presence in the region.
The new varieties complement Origin's existing commercial portfolio, including Zhongdan 6202 and Bangzhongbang 889, as the Company continues to introduce new products across its major markets.
Advancing Breeding Innovation and Commercialization
The preliminary review of the three varieties represents another milestone in Origin's breeding and commercialization program. The Company continues to strengthen its breeding capabilities through a combination of proprietary germplasm, conventional breeding, biotechnology, gene-editing technologies, and AI-assisted breeding tools.
With an expanding portfolio of commercial and pipeline varieties, Origin is focused on improving its ability to deliver high-performing corn varieties to farmers while expanding its geographic coverage across China's major corn-producing regions.
