Description:

LIGHTSPROUT: small, ovoid, medium number of root tips, short lateral shoots
LIGHTSPROUT BASE: medium to strong intensity of anthocyanin colouration, medium proportion of blue in anthocyanin colouration, medium to dense pubescence
LIGHTSPROUT TIP: medium size in relation to base, closed habit, absent or very weak intensity of anthocyanin colouration, sparse pubescence

PLANT: foliage structure is intermediate type to leaf type where foliage is half open to closed and stems are partly to hardly visible, semi-upright growth habit, high frequency of flowers, matures mid to late in the season

STEM: absent or very low extent of anthocyanin colouration at base of stem

LEAF: large outline, intermediate to open openness, weak presence of secondary leaflets, light to medium green upper side, low extent of very weak to weak intensity anthocyanin colouration on upper side of midrib, absent or very low frequency of coalescence of terminal and lateral leaflets
SECOND PAIR OF LATERAL LEAFLETS: large, leaflet is narrower than long
LEAFLET: weak to medium degree of waviness of margin, veins of medium depth, dull upper side, pubescence present on blade of apical rosette

PEDUNCLE: absent or very low extent of anthocyanin colouration
INFLORESCENCE: medium sized
FLOWER BUD: absent or very low extent of anthocyanin colouration
COROLLA: medium sized
COROLLA (INNER SIDE): absent or very weak intensity of anthocyanin colouration, absent or low proportion of blue in anthocyanin colouration, absent or very low extent of anthocyanin colouration

TUBER: long oval, light yellow flesh
TUBER EYE: shallow, yellow at base
TUBER SKIN: light beige, weak intensity of anthocyanin colouration in reaction to light

Origin & Breeding History: 'Linus' (experimental designation 479 201-08) originated from the cross between '66 109-01' as the female parent and '1084 202-00' as the male parent conducted at the NORIKA Nordring-Katoffelzucht und Vermehrungs GmbH Gross Lüsewitz breeding station in Gross Lüsewitz, Germany in 2007. One of the resulting progeny was selected and designated 479 201-08 in 2014 based on yield, internal quality, tuber shape and uniformity and disease resistance.

Tests & Trials: The comparative trial for 'Linus' was conducted by Global Agri Services Inc. in Central Blissville, New Brunswick during the 2023 growing season. The field trial consisted of a single 15.2 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.
