The base of the lightsprout of ‘FL2637' has very sparse to sparse pubescence while that of ‘Snowden' has sparse to a medium density pubescence. The lightsprout apex of ‘FL2637' has a strong intensity of anthocyanin colouration and a medium density of pubescence while that of ‘Snowden' has an absent or very weak intensity of anthocyanin colouration and very sparse to sparse pubescence. The lightsprout of ‘FL2637' has few to a medium number of root tips while that of ‘Snowden' has many root tips. The stem of ‘FL2637' has a medium extent of anthocyanin colouration while that of ‘Snowden' has an absent or very low extent of anthocyanin colouration. The plants of ‘FL2637' have a medium number of medium sized inflorescences while those of ‘Snowden' have very few to few very small inflorescences. The plants of ‘FL2637' are shorter than those of ‘Snowden'.

Origin & Breeding History: 'FL2637' (experimental designation 286.04) originated from the cross between the varieties ‘FL2312', as the female parent and ‘FL2492', as the male parent, conducted at the Frito-Lay Agriculture Research and Development Facility near Rhineland, Wisconsin, USA in 2015. The new variety was designated 286.04 in 2017 based on negative mass selection for agronomic characteristics including appearance, tuber set and flesh colour. Further evaluations were conducted in subsequent years assessing specific gravity, chip processing from both field and storage as well as disease resistance.

Tests & Trials: The comparative trial for 'FL2637' was conducted by Global Agri Services Inc. in Central Blissville, New Brunswick during the 2025 growing season. The field trial consisted of a single 16-metre-long row for each variety, with rows spaced 1.1 metres apart. Each row contained 70 plants spaced 0.23 metres apart. Measurements were taken from 10 plants, or 10 parts of plants, of each variety. The mean differences were significant at the 5% confidence probability level based on a paired Student's t-test. Lightsprout characteristics were assessed on 10 tubers harvested from the comparative trial and observed approximately 2.5 to 3 months after sprouting was promoted by exposing the tubers to an external agent.
