Variety Description

Varieties used for comparison: 'Aquilon', 'Atlantic', 'AC Novachip' and 'Niska'

Summary: 'FG100' differs mainly from the reference varieties by plant height, leaf size, intensity of anthocyanin colouration of the flower bud and corolla, corolla colour and tuber and light sprout shape. 'FG100' is taller than all of the reference varieties. The leaves of 'FG100' are longer and wider than those of 'AC Novachip' and they are shorter and more narrow than those of 'Aquilon' and 'Atlantic'. The anthocyanin colouration of the flower bud and corolla is more intense for 'FG100' than the reference varieties. 'FG100' has a blue-violet corolla colour while it is white for 'Aquilon', 'AC Novachip' and 'Niska' and pale lavender for 'Atlantic'. The tuber shape for 'FG100' is round oblong while it is oval for 'Aquilon' and 'Niska' and round oval for 'Atlantic' and oblong oval for 'AC Novachip'.


PLANT: semi-upright to spreading growth habit, stem type foliage structure, mid-season maturity
STEM: medium anthocyanin colouration, medium thickness, nodes with low swelling

LEAVES: light green, intermediate silhouette, absent or very weak anthocyanin colouration on upper side of rachis, weak anthocyanin colouration on the petiole, shallow veins, weak waviness of margin, medium glossiness on upper side, pubescence present on leaves of apical rosette, weak to medium presence of secondary leaflets
TERMINAL LEAFLET: medium ovate shape, acuminate tip, cordate base, absent or very low frequency of coalescence with lateral leaflets
LATERAL LEAFLET: small to medium in size, medium ovate shape, acuminate tip, lobed base

INFLORESCENCE: high flowering profusion, medium size, flower buds are persistent, very strong anthocyanin colouration of flower bud
COROLLA: blue-violet, medium large, prominant star, very strong anthocyanin colouration of inner side and weak to moderate anthocyanin colouration on the peduncle

TUBER: round oblong
TUBER SKIN: light beige, white at base of eye, absent or very weak anthocyanin colouration in reaction to light, smooth to rough texture
TUBER EYES: shallow, even distribution, slight prominence of eyebrows
TUBER FLESH: white, no secondary colour

LIGHT SPROUT: medium size, ovoid to conical shape, medium number of root tips, medium length lateral shoots
BASE: weak to medium anthocyanin colouration, high proportion of blue in anthocyanin colouration, weak pubescence
TIP: smaller than base in size, closed to intermediate habit, medium to strong anthocyanin colouration, sparse pubescence

Origin & Breeding History: 'FG100' originated from the cross between 'W-876' and 'LD20-6' in 1990. The variety remained in the selection process for 8 years before being presented to industry in 1999. The selection criteria included chipping quality, high specific gravity and yield. The variety was ready for experimental research in 2001.

Tests & Trials: Trials for 'FG100' were conducted in Pont Rouge, Quebec in 2007. All entries were planted in single-row plots. There were 2 rows of each variety with each row containing approximately 15 plants which were spaced 25 cm apart. Measured characteristics were based on 10 measurements.
