Washington fields free of modified wheat

Washington wheat is free of the genetically modified herbicide resistance found in an Oregon crop earlier this year, researchers at Washington State University announced Tuesday.

The discovery of modified wheat in Oregon ignited trade restrictions that took months to resolve. Japan recently decided to resume importing wheat grown in the Pacific Northwest.

The WSU research project included tests on 74 wheat varieties from universities and companies. The tests also included 1,900 advanced breeding lines from WSU and more than 20,000 individual plots.
