Bangladeshi scientists seek regulatory approval for a GMO potato resistant to late blight

Scientists in Bangladesh (BARI) have successfully field-tested a genetically modified (GMO) potato resistant to late blight, one of the most devastating potato diseases. Once the regulatory trial is over in February, they will apply for release of the variety.

Simplot's Second Generation Innate® Potato Receives FDA Safety Clearance

The Food and Drug Administration has completed its food and feed safety assessment of the J.R. Simplot Company’s second generation of Innate® potatoes. Simplot will still need to complete its registration with the Environmental Protection Agency for these potatoes before introducing them for sale in the U.S. marketplace.

Resistance genes of wild potato relatives offer help in combat against Phytophthora

Research shows that crops with stacks of two or more resistance genes from closely related species, introduced into the crop via for instance genetic engineering, combined with the simultaneous introduction of resistance management, can ensure the long-term resistance of these plants to economically significant and aggressive diseases.

USDA Deregulates Second Generation Innate™ GMO Potatoes

The J.R. Simplot Company is pleased that the USDA has deregulated the Russet Burbank variety of the second generation of Innate™ potatoes. Simplot is looking forward to the completion of the EPA registration and FDA consultation before the second generation of Innate™ potatoes can be introduced into the marketplace.
