Variety used for comparison: 'FL2385'

Summary: The base of the lightsprout for 'FL2387' has a medium density of pubescence whereas that of 'FL2385' has sparse pubescence. In relation to the base, the lightsprout tip of 'FL2387' is medium in size whereas it is small for 'FL2385'. The lightsprout tip of 'FL2387' has an intermediate habit and medium to dense pubescence whereas that of 'FL2385' has a closed habit and sparse pubescence. The upper side of the leaf of 'FL2387' is light green with a low extent of anthocyanin on the midrib whereas the leaf of 'FL2385' is medium to dark green with a high extent of anthocyanin colouration on the midrib. The extent of anthocyanin colouration on the flower bud of 'FL2387' is low to medium whereas it is high for 'FL2385'. The plants of 'FL2387' are shorter than those of 'FL2385'. The intensity of anthocyanin colouration on the inner side of the corolla of 'FL2387' is strong to very strong whereas it is medium to strong for 'FL2385'. In reaction to light, the anthocyanin colouration on the tuber skin is strong for 'FL2387' whereas it is weak to medium for 'FL2385'.

Origin & Breeding History: 'FL2387' (experimental designation 2008 6.03) originated from the cross between '2001 312.08' and 'FL 1922' conducted in 2007 at the Frito-Lay Research and Development Facility near Rhineland, Wisconsin, USA. Seed resulting from the cross was grown in a greenhouse and the resulting seed tubers field planted in 2008. One progeny, designated as 2008 6.03, was identified in 2008. Selection criteria were based on negative mass selection for agronomic characteristics, disease resistance and fry colour after tuber storage.

Tests & Trials: The comparative trial for 'FL2387' was conducted by Global Agri Services Inc. during the 2018 growing season in Drummond, New Brunswick. The trial consisted of a single, 21 metre long row containing 70 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. The mean difference was significant at the 5% probability level based on a paired Student's t-test.
