The Nebraska Crop Improvement Association, with offices on UNL's East Campus, tests and certifies wheat seed to assure it meets quality standards. In 2013 NCIA inspected 25,562 acres of hard red winter wheat for certified seed production. Their fall 2013 guide for certified seed and providers is available at http://www.necrop.org/SEED%20BOOKS/2013fallLarge.pdf.
