A new potato variety, that’s genetically modified to withstand bruising, has been cleared for commercialization, without undergoing USDA’s deregulatory process for biotech crops. The agency has advised the potato’s developer, Calyxt, that the cultivar is not a “regulated article” under federal law because it doesn’t contain genes from plant pests.
Because most commercial biotech crops incorporate genes from plant pests, they were subject to environmental analysis and a risk assessment from USDA before they were deregulated.
In the case of Calyxt’s “PPO_KO” potato, the variety was created through the “knockout” of an unwanted gene that causes bruising, without leaving plant pest genes in the crop.
The cultivar will reduce browning in fresh potatoes as well as bruising “to minimize crop rejection and waste in processing lines,” said Federico Tripodi, Calyxt’s CEO, in an email. Up to 5 percent of fries and chips are rejected because of discoloration, he said.
With the USDA’s recent approval, the company plans to work with “third party researchers” to plant the variety in U.S. fields, he said.
