Argentina has become the first country to approve the growth and consumption of genetically modified wheat.

The country's National Commission for Science and Technology (CONICET) said it had approved a drought-resistant variety of wheat known as HB4.

Argentina is the world's fourth-largest exporter of the crop.

Despite the decision, some are concerned that GMO (genetically modified organisms) products like wheat could have adverse environmental or health impacts. Some agricultural groups are also concerned it could stigmatise Argentinian produce on global markets.

CONICET admitted that the wheat would also have to be approved in Brazil, historically the country's biggest export market, to be commercially viable.

Argentina has become the first country to approve the growth and consumption of genetically modified wheat, the Agriculture Ministry announced.

In a statement released by the portfolio, the Consejo Nacional de Investigaciones Científicas y Técnicas de Argentina (National Commission for Science and Technology, CONICET) said that it had approved a drought-resistant variety of wheat in the world's fourth-largest exporter of the crop.

"This is the first approval in the world for drought-tolerant genetic transformation in wheat," read the communiqué.

However, experts expressed concern about the growth and marketing of genetically modified crops (GMOs), citing difficulties in marketing such produce to consumers concerned about their effect on health and the environment.

CONICET said the genetic modifications to Argentina's wheat crop would have to be approved in Brazil, historically the country's biggest export market, to be commercially viable.

Some 45 percent of Argentina's wheat exports in 2019 went to Brazil. Other key markets are Indonesia, Chile and Kenya.

The formal government approval is due to be published on Thursday or Friday in the Official Gazette, an official source told AFP, adding that it has "already been signed by the Agriculture Ministry.

The drought-resistant HB4 wheat variety was developed by local biotechnology company Bioceres, working with the Universidad Nacional del Litoral and CONICET.

"Approval of our HB4 wheat in Argentina represents a groundbreaking milestone for the entire global value chain of this important crop, given the substantial yield increases and significant environmental benefits that our technology offers," said Bioceres CEO Federico Trucco.

"Now we must go out into the world and convince people that this is super good and be able to generate markets for this wheat, which represents an evolutionary leap," he added.

“Today Argentina is leading technological transformation at an international level,” Trucco said.

“HB4 technology provides seeds that are more tolerant to drought, minimising production losses, and giving greater predictability to yields,” the Agriculture Ministry said in the statement.

Trucco admitted that winning approval from Brazil may be difficult.

"The first country we have to convince is Brazil, and it may be hard work," he said.

The news was not received well across the board. Environmental activists have expressed concern over the move, while experts members of the National Seed Institute's Winter Cereals Committee also cautioned against the use of GM seeds.

In a letter released Thursday, they warned that no country approved the use of transgenic wheat varieties "due to the non-acceptance by local and/or foreign consumers of products made with transgenic crops and the difficulty of keeping GMO and non-GMO production separate."

They said eventual approval by the Brazilian government "does not guarantee that mills, bakeries and individual consumers will agree to buy our GMO wheat and if they do, there is not guarantee that they will do so without a price discount."

The experts acknowledged the modified HB4 trait was a scientific advance and could make an important contribution to soybeans, maize and other crops, "but for now, not to wheat."

In a decade of field trials for the HB4 wheat varieties returned an average 20 percent yield improvement in drought situations.

Severe droughts have increased in frequency as climate change worsens.

The Buenos Aires Grain Exchange said last month that wheat yields are being cut in half in areas of Argentina that have been devastated by drought.
