Summary: The base of the lightsprout of 'Soprano' has a medium intensity of anthocyanin colouration with an absent or very low proportion of blue and dense to very dense pubescence while the base of the lightsprout of 'Bintje' has a very strong intensity of anthocyanin colouration with a high proportion of blue and sparse pubescence. 'Soprano' has a lightsprout tip that is smaller in size in relation to the base and sparse pubescence while for 'Bintje' it is medium sized in relation to the base with medium pubescence. The lightsprout of 'Soprano' has a medium number of root tips while there are few for 'Bintje'. The midrib on the upper side of the leaf of 'Soprano' has an absent or very low extent of very weak anthocyanin colouration while the midrib of 'Bintje' has a low extent of weak anthocyanin colouration. The extent of anthocyanin colouration on the flower bud of 'Soprano' is absent or very low while it is high for 'Bintje'. 'Soprano' has a taller plant height than 'Bintje'. 'Soprano' has a low frequency of inflorescences per plant while 'Bintje' has a medium frequency. The extent of anthocyanin colouration on the peduncle of 'Soprano' is absent or very low while it is medium for 'Bintje'.

Origin & Breeding History: The origin of 'Soprano' is the result of a cross made in 1996 between 'Spunta' and CMK1990-002-002 at Rilland, The Netherlands. The selection criteria included yield, appearance, maturity, disease resistance and quality characteristics.
Tests & Trials: Tests and trials were conducted during the 2011 growing season in Drummond, New Brunswick. Plots consisted of 60 plants grown in a single row with a row length of 18.5 meters and a row spacing of 0.9 meters.
