The lightsprout tip of 'Delphine' is medium sized in relation to the base with very sparse pubescence while it is small in 'Chieftain' with dense pubescence. 'Delphine' has a few root tips on the lightsprout while 'Chieftain' has a medium number. The foliage structure of 'Delphine' is an intermediate type while it is a leaf type in 'Chieftain'. 'Delphine' has a taller plant height than 'Chieftain'. 'Delphine' has a medium sized leaf with an open leaf outline while the leaf of 'Chieftain' is large with intermediate openness. The extent of anthocyanin colouration on the midrib of the upper side of the leaf in 'Delphine' is very high while it is high in 'Chieftain'. 'Delphine' has a medium to high frequency of coalescence of the terminal and lateral leaflets while it is absent or very low in 'Chieftain'. The pubesence of the blade at the apical rosette of 'Delphine' is present while it is absent for 'Chieftain'. 'Delphine' has a low frequency of inflorescences per plant while it is high in 'Chieftain'. The inflorescence of 'Delphine' is small and has a medium extent of anthocyanin colouration on the peduncle while the inflorescence of 'Chieftain' is medium sized with a high extent of anthocyanin colouration on the peduncle. 'Delphine' has a weak intensity of anthocyanin colouration on the inner side of the corolla while it is medium to strong in 'Chieftain'.

Origin & Breeding History: The origin of 'Delphine' is the result of the cross made in 1994 between KE 48 and 'Caesar' at Bad Schwartau, Germany. The selection criteria included maturity, yield, disease resistance, processing traits, morphological traits and storage 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.
