Durably resistant potatoes with wild potato genes offer 80% reduction in chemical control

Research to develop potatoes with sustainable resistance against phytophthora via genetic modification with genes from wild potatoes and good resistance management ended with the publication of the scientific results. The approach resulted in potato plants which require 80% less chemical control.

Lower Yield and Quality will determine potato market in the Netherlands, says farmer association

The Dutch Association of Arable Farmers of (VTA) finds an average yield of 53.622 kg/ha, 8% below last year and on par with the 5-year average. Although tubers are large this season, the VTA predicts low factory yields as a result of a host of quality issues, resulting in an increased demand for potatoes per ton finished product.

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.
