KingAgroot Receives GMO Safety Certificate and Newly Developed Corn Varieties Pass Certification

Recently, KingAgroot CropScience has achieved two significant milestones: obtaining the Agricultural GMO Safety Certificate (for production application) for its insect-resistant and herbicide-tolerant corn transformation event QY2569-42, and receiving approval for its first series of independently developed “Qingtianyu” corn varieties. These achievements mark a new chapter in KingAgroot’s biotech breeding program.

First Series of “Qingtianyu” Corn Varieties Passes National Certification

On December 31, the Ministry of Agriculture and Rural Affairs Announcement No. 867 published multiple crop varieties approved for 2024, including KingAgroot’s first series of “Qingtianyu” corn varieties. 

Seven corn varieties in the “Qingtianyu” series received national certification: Qingtianyu 503, Qingtianyu 702, Qingtianyu 704, Qingtianyu 801, Qingtianyu 806, Qingtianyu 808, and Qingtianyu 811. These varieties cover major maturity groups including Northern China early-maturing varieties, Northeast China medium-early maturing varieties, Northeast China medium-maturing varieties, Northeast China medium-late maturing varieties, and Huang-Huai-Hai Plain summer-planted varieties.

KingAgroot Obtains First GMO Safety Certificate

On December 31, KingAgroot's transgenic corn event QY2569-42 received its safety certificate (Agricultural GMO Safety Certificate [2024] No. 287) from the Ministry of Agriculture and Rural Affairs, marking the company's first GMO safety certificate.

The QY2569-42 transformation event expresses two lepidopteran pest-resistant genes, vip3Aa-k1 and cry1Ab, along with the pat gene conferring tolerance to glufosinate and L-glufosinate. The vip3Aa-k1 gene, independently developed by KingAgroot with proprietary intellectual property rights, demonstrates high expression in corn and strong resistance to fall armyworm without adverse effects on the crop. This development successfully addresses the industry’s technical challenge of achieving high expression while managing expression compensation. The vip3Aa-k1 gene, combined with cry1Ab, provides robust resistance against all lepidopteran pests in corn.

Seeds, serving as the “microchips” of agriculture, are crucial for national food security. Driven by a strong sense of mission, KingAgroot focuses on two key areas: new compound creation and biotech breeding, working to enhance both agricultural production efficiency and quality. 

Looking ahead, KingAgroot will accelerate the commercialization of “Qingtianyu” seeds featuring herbicide tolerance, insect resistance, and disease resistance. The company will continue to strengthen the synergistic effects between patented pesticides, transgenic traits, and patented seeds, building a complete closed-loop industrial chain to reinforce national food security through technological innovation.
