Origin & Breeding History: 'Targhee Russet' originated from a cross conducted in 2001 between 'A92303-7'' and 'A96004-8' at the University of Idaho Research and Extension Center, in Aberdeen, Idaho. 'Targhee Russet' was selected in 2002 for its positive agronomic characteristics and resistance to various diseases.
Tests & Trials: The comparative trial for 'Traghee Russet' was conducted by Global Agri Services Inc. during the growing season of 2016 in Drummond, New Brunswick. The trial consisted of a single, 19.5 metre long row containing 65 plants spaced 0.3 metres apart for each variety. The distance between rows within the trial was 0.9 metres. Observations and measurements were taken from 10 plants, or 10 parts of plants, of each variety.
