The stem of ‘FL2602' has a medium to high extent of anthocyanin colouration while that of ‘FL2204' has a very low to low extent of anthocyanin colouration. The upper side of the midrib on the leaf of ‘FL2602' has a strong intensity of anthocyanin colouration while that of ‘FL2204' has an absent or very weak intensity of anthocyanin colouration. The peduncle of ‘FL2602' has a high extent of anthocyanin colouration while that of ‘FL2204' has an absent or very low extent of anthocyanin colouration. The corolla of ‘FL2602' has a large to very large diameter while that of ‘FL2204' has a medium diameter. The tuber of ‘FL2602' is round and has a medium skin texture while that of ‘FL2204' has a short-oval form and smooth skin.

Origin & Breeding History: 'FL2602' (experimental designation 2016 435.01) originated from the cross between ‘FL2452' and 'FL2204', conducted at the Frito-Lay Agriculture Research and Development facility near Rhinelander, Wisconsin, United States in 2015. One of the resulting progeny was designated 2016 435.01 in 2016 based on yield, disease resistance, and chipping potential.

Tests & Trials: The comparative trial for 'FL2602' was conducted by Global Agri Services Inc. in Central Blissville, New Brunswick during the 2024 growing season. The field trial consisted of a single 14.86 metre long row per variety. Rows were spaced 1.1 metres apart with each row containing 65 plants spaced 0.23 metres apart. Measurements were taken from 10 plants, or 10 parts of plants, of each variety. 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.
