Origin & Breeding History: 'Pomerelle Russet' (experimental number A02062-1TE) originated from a cross conducted between 'A97201-4' and 'A97299-1' in 2002 at the University of Idaho Research and Extension Center in Aberdeen, Idaho. 'Pomerelle Russet' was selected in 2004 for its positive agronomic characteristics and resistance to various diseases.

Tests & Trials: The comparative trial for 'Pomerelle 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. Mean differences were significant at the 5% probability level based on a paired Student's t-test.
