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.

LEAVES: medium green, open silhouette, medium anthocyanin colouration on upper side of rachis and petiole, deep veins, absent or very weak waviness of margin, medium glossiness on upper side, slight pubescence on leaves of apical rosette, medium presence of secondary leaflets
TERMINAL LEAFLET: medium ovate shape, acuminate tip, obtuse to cordate base, absent or very low frequency of coalescence with lateral leaflets
LATERAL LEAFLET: medium size, narrow ovate shape, acute to acuminate tip, cordate base

INFLORESCENCE: high flowering profusion, medium size, flower buds persist, absent or very weak anthocyanin colouration of flower bud
COROLLA: red-violet, medium size, prominant star, strong anthocyanin colouration of inner side and medium anthocyanin colouration on peduncle

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.
