FL2312

Potato

Variety Description

Variety used for comparison: 'Atlantic'

Summary: 'FL2312' has a small and spherical lightsprout whereas it is medium sized and ovoid for 'Atlantic'. The lightsprout tip of 'FL2312' has sparse pubescence and strong anthocyanin colouration whereas that of 'Atlantic' has dense pubescence and weak anthocyanin colouration at the tip. The foliage structure of 'FL2312' is an intermediate type (foliage half open, stems partly visible) whereas 'Atlantic' is a leaf type (foliage closed, stems not, or hardly visible). The extent of anthocyanin colouration is low halfway up the stem for 'FL2312' whereas it is absent for 'Atlantic'. The leaflet blade at the apical rosette is pubescent for 'FL2312' whereas it is glabrous in 'Atlantic'. 'FL2312' has a taller plant height than that of 'Atlantic'. The extent of the anthocyanin colouration is medium to high on the peduncle and absent or very low on the inner side of the corolla for 'FL2312' whereas the extent of the anthocyanin colouration is absent or very low on the peduncle and high on the inner side of the corolla for 'Atlantic'. The tubers of 'FL2312' have a yellow skin and white flesh whereas the skin is light beige and the flesh is cream in colour for the 'Atlantic' tubers.

LIGHTSPROUT TIP: large size in relation to base, closed habit, strong intensity of anthocyanin colouration, sparse pubescence

PLANT: foliage structure is an intermediate type where foliage is half open and stems are partly visible, semi-upright growth habit, early maturity

STEM: low extent of anthocyanin colouration halfway up the stem

LEAF: medium outline, intermediate to open, medium green colour, low extent and absent or very weak intensity of anthocyanin colouration on the midrib of the upper side
SECOND PAIR OF LATERAL LEAFLETS: medium to large, narrower than long width in relation to length
LEAFLETS: medium presence of secondary leaflets, absent or very low frequency of coalescence of terminal and lateral leaflets, medium waviness of margin, medium to deep veins, dull on upper side, pubescence on blade at apical rosette

INFLORESCENCE: high frequency per plant, large, medium to high extent of anthocyanin colouration on peduncle
FLOWER BUD: medium extent of anthocyanin colouration
COROLLA: medium size, absent or very low extent and absent or very weak intensity of anthocyanin colouration on the inner side, absent or low proportion of blue in the anthocyanin colouration

TUBER: short oval shape, white flesh
TUBER EYE: shallow depth, yellow at base
TUBER SKIN: yellow, absent to weak anthocyanin colouration in reaction to light

Origin & Breeding History: The variety 'FL2312' (experimental designation 2005 158.01) originated from a cross made in 1997 between 'FL 1924' as the female parent and 'Andover' as the male parent at the Frito-Lay Agricultural Operations and Development facility near Rhinelander, Wisconsin, USA. Seed from the cross was sown in the greenhouse near Rhinelander. Seedlings were transplanted to pots outdoors in June 2004. The resulting tubers were harvested and planted in the field in the spring of 2005. One of the selected progeny was given the designation as 2005 158.01. Selection criteria were negative mass selection for agronomic characteristics and resistance to various diseases.

Tests & Trials: Trials for 'FL2312' 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.
