(Bloomberg) -- China has approved dozens of genetically modified corn and soybean seed varieties for planting, in a breakthrough move that could eventually boost production and reduce dependence on foreign supplies.

The country is the world’s top importer of soybeans and corn. Large-scale marketing of GM crops would support the government’s drive for food self-sufficiency and security, a top priority for President Xi Jinping.

A national committee set up by the agriculture ministry has approved 37 GM corn seed and 14 soybean seed varieties, after a preliminary review, the ministry said on Tuesday.

The approved list, including four corn varieties developed by China National Seed Group, a unit of Syngenta Group, and five soybean varieties from Beijing Dabeinong Technology Group, is available for public review until Nov. 15.  

Actual planted areas for these seed varieties, after final approval, should be in accordance with relevant government arrangements, according to the notice on the website of the Ministry of Agriculture and Rural Affairs.

Planting Expands

China started a pilot program for commercial planting of GM corn and soybean crops in 2021 and has expanded the trial to 20 counties in five provinces including major grain producers Hebei and Jilin this year, state media reported, citing an official from the agriculture ministry. 

The acreage designated for planting the GM crops is still very small, however, reaching just 4 million mu (267,000 hectares) this year, state media reported. 

Corn area alone in China is about 44 million hectares, with output of over 288 million tons likely in the 2023-24 year, according to the agriculture ministry. While productivity lags far behind the US, where GM varieties are widely grown, such seeds can increase yields in China by as much as 12%, the ministry said. 

Chinese seed company shares were among the country’s best performing stocks. Dabeinong surged 10% to the limit, while Yuan Longping High-tech Agriculture Co. was up more than 8%. The national market for GM corn seed may be worth as much as 60 billion yuan ($8.2 billion), according to some industry estimates.
