Summary: 'Romanze' has an upright growth habit while 'Asterix' has a semi-upright growth habit. 'Romanze' has a shorter plant height than 'Asterix'. The terminal and lateral leaflets of 'Romanze' have no or a very low frequency of coalescence while it is high for 'Asterix'. 'Romanze' has large, broad cylindrical light sprouts while they are medium ovoid for 'Asterix'. The intensity of anthocyanin colouration of the light sprout tips is strong for 'Romanze' while it is weak for 'Asterix'. 'Romanze' has medium length lateral shoots while they are short for 'Asterix'.

Origin & Breeding History: 'Romanze' originated from the cross of '3.14 104-90' and 'Rasant', made in GroB Lüsewitz, Germany in 1995. The selection criteria were maturity, yield, resistance, processing traits, morphological traits, and storage characters.
Tests & Trials: Trials for 'Romanze' were conducted in Drummond, New Brunswick in 2007. All entries were planted in single-row plots. Plots consisted of rows 22 meters long with 30 cm in row spacing between plants and spacing between rows of 91 cm. Measured characteristics were based on 10 measurements. Colour determinations were made using the 1986 RHS colour chart.
