Variety Description
Varieties used for comparison: 'Hinnomaki Red' and 'Invicta'
Summary: The shoots of 'Rafzuera' have a more horizontal attitude than those of 'Hinnomaki Red'. 'Rafzuera' has fewer basal shoots and fewer prickles and bristles than both reference varieties. The leaves of 'Rafzuera' are narrower with a shorter mid-rib and a shorter petiole than both reference varieties. 'Rafzuera' has predominantly one flower per inflorescence while both reference varieties have two. The anthocyanin colouration of the sepals and ovary of 'Rafzuera' are weaker than those of 'Invicta' and stronger than those of 'Hinnomaki Red'. 'Rafzuera' has larger fruit than both reference varieties. The fruit of 'Rafzuera' is globose while it is ellipsoid for 'Invicta'. The hairiness on the fruit of 'Rafzuera' is absent or very sparse while it is medium to dense for 'Invicta'. 'Rafzuera' has longer elongation of the base of the fruit than 'Hinnomaki Red'.

Origin & Breeding History: 'Rafzuera' (experimental designation 'ICS 90-2') originated from a cross pollination made in Rafz, Switzerland, between the variety 'Invicta' (female) and a private selection designated 'LS 9-31-54' (male) in 1990. The selection criteria for 'Rafzuera' were based on fruit size and colour, and earliness of ripening.
Tests & Trials: Trials for 'Rafzuera' were conducted during 2003 and 2004 in Courtenay, British Columbia. Each plot consisted of 2 rows, 48 metres long and 2.7 metres apart. There were 160 plants spaced 60 cm apart within rows.
