Origin & Breeding History: The origin of 'Abbot' (experimental designation CMK1998-601-035) is the result of the cross made in 1997 between 'Asterix' as the female parent and 'RH88-025-050' as the male parent at the C. Meijer B.V. Breeding Station in Rilland, The Netherlands. Selection criteria were yield, tuber appearance, storability and disease resistance.

Tests & Trials: Tests and trials for 'Abbot' were conducted during the 2012 growing season in Drummond, New Brunswick. Each plot per variety 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.
