Origin & Breeding History: The variety 'Palisade Russet' originated from a cross between 'AWN86514-2' as the female parent and 'A86102-6' as the male parent, made at the University of Idaho's Aberdeen Research and Extension Center in 2000. The variety was selected as a seedling in the field in 2001 at Aberdeen, Idaho. Selection criteria were negative mass selection for agronomic characteristics and resistance to various diseases.

Tests & Trials: Trials for 'Pallisade Russet' were conducted during the 2013 growing season in Drummond, New Brunswick. Each variety plot consisted of 60 plants grown in a single row with a row length of 18.5 metres and a row spacing of 0.9 metres between rows. Plants were spaced 0.30 metres apart. The measured characteristics were based on 10 measurements per variety. Mean differences were significant at the 5% probability level based on a paired Student's t-test.
