China Approves Syngenta-Developed Maize Traits for Cultivation
The Chinese Ministry of Agriculture has approved three applications made by the China National Seed Group (CNSG) for GM maize traits in the country that have not previously been approved for use.
The first is in Southern and South-West maize regions of China for Bt11 x MIR162 x GA21 (marketed as Agrisure Viptera 3110 in North America), a stack that was originally developed by Syngenta and launched in the USA in 2011. The trait stack provides lepidopteran insect pest resistance through expression of the Cry1Ab gene, coleopteran pest resistance via mCry3A, glyphosate herbicide tolerance by use of the mepsps gene, and glufosinate tolerance conferred by the pat gene. Maize varieties utilising the technology will allow the control or suppression of pests such as European Corn borer, Southwestern Corn borer and Corn Rootworm.
CNSG has also received approval for use of the trait stack Bt11 x GA21 (marketed as Agrisure GT/CB/LL in North America) in the Northern spring maize region. The technology was first introduced in the USA in 2005, providing lepidopteran resistance through the expression of the Cry1Ab gene, while also possessing tolerance to glyphosate and glufosinate. The GA21 glyphosate herbicide tolerant trait has also received approval for use in the Northern Spring maize region. The trait was first launched in the USA 1998 and, when used as a stand-alone trait, is utilised in maize seed refuge areas.
CNSG was consolidated into the Syngenta group in 2020 and forms part of the group's Chinese seed activities, which also include Syngenta and Winall Hi-tech.
