Variety Description

Variety used for comparison: 'Yukon Gold'

Summary: The lightsprout of 'Smart' has a broad cylindrical shape whereas the lightsprout of 'Yukon Gold' is spherical. The intensity of anthocyanin colouration at the base of the light sprout is very strong with a high proportion of blue for 'Smart' while it is a medium intensity with an absent or low proportion of blue for 'Yukon Gold'. The lightsprout tip of 'Smart' is small in relation to the base whereas it is medium sized in 'Yukon Gold'. 'Smart' has a semi-upright to spreading growth habit whereas 'Yukon Gold' has an upright to semi-upright growth habit. The plant of 'Smart' is shorter than that of 'Yukon Gold'. The extent of anthocyanin colouration on the inner side of the flower corolla of 'Smart' is absent or very low whereas it is high for 'Yukon Gold'. The intensity of anthocyanin colouration on the inner side of the flower corolla of 'Smart' is absent or very weak whereas it is weak to a medium for 'Yukon Gold'.

Origin & Breeding History: The origin of 'Smart' is the result of the cross made in 1997 between 'Lady Felicia' as the female parent and 'Secura' as the male parent at the HZPC Research & Development Centre in Metslawier, The Netherlands. Selection criteria included internal and external quality, yield and resistances against different diseases and pests.

Tests & Trials: Tests and trials for 'Smart' 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.
