LIGHTSPROUT TIP: medium size in relation to base, intermediate habit, absent to weak intensity of anthocyanin colouration, medium pubescence

PLANT: stem to intermediate type foliage structure where foliage is open or half open and stems are clearly to partly visible, semi-upright growth habit, late maturity

STEM: medium extent of anthocyanin colouration halfway up the stem

LEAF: large outline, intermediate to open, medium green colour, low extent and weak intensity of anthocyanin colouration on the midrib of the upper side
SECOND PAIR OF LATERAL LEAFLETS: large size, 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, weak waviness of margin, medium depth of veins, medium glossiness of upper side, pubescence on blade at apical rosette

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

Origin & Breeding History: The origin of 'Lanorma' is the result of the cross made in 1991 between 'Byland' as the female parent and 'Caesar' as the male parent in Houwerzijl, The Netherlands. Selection criteria included maturity, yield, disease resistance, processing traits, morphological traits and storage characters.

Tests & Trials: Tests and trials for 'Lanorma' were conducted during the 2012 growing season in Drummond, New Brunswick. Each plot per variety 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.
