Variety Description
Varieties used for comparison: 'Laura' and 'Asterix'
Summary: 'Tizia' has an upright growth habit while 'Asterix' has a semi-upright growth habit. 'Tizia' has a longer leaf than the reference varieties. The leaf of 'Tizia' is wider than the leaf of 'Laura' and not as wide as the leaf of 'Asterix'. 'Tizia' has no or a very low frequency of coalescence for the terminal and lateral leaflets while the refence varieties have a high to very high frequency of coalescence. The light sprout base of 'Tizia' has lower anthocyanin colouration and sparser pubescence then those of the reference varieties.

Origin & Breeding History: 'Tizia' originated from a cross between 'L 89-975' and 'Laura', made in Kaltenberg, Germany in 1994. The selection process was based on negative agronomic criteria.
Tests & Trials: Trials for 'Tizia' were conducted in Drummond, New Brunswick in 2007. All entries were planted in single-row plots. Plots consisted of rows 22 metres 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.
