Summary: 'Fiero' is an early maturing sport of 'Fuji' which matures approximately 4 to 6 weeks earlier than 'Fuji BC2'and 2 weeks earlier than 'Royal Gala' in the Okanagan valley. 'Fiero' differs from both reference varieties in the intensity and pattern of the fruit overcolour. 'Fiero' has dark red overcolour in a solid flush, whereas the overcolour of 'Royal Gala' and 'Fuji BC2' is a medium red with striping as well as flush patterns. The fruit of 'Fiero' also has a heavier bloom on the skin than either of the reference varieties.

ONE-YEAR OLD SHOOT: thin to medium thickness, short to medium internode, medium pubescence, many lenticels, reddish brown on sunny side

MATURE LEAF: upwards orientation

Origin & Breeding History: The variety 'Fiero' was discovered as a whole tree mutation in a block of an early 'Fuji' strain being grown in a cultivated area at the Broetje Orchards in Prescott, Washington. This single tree, planted in 1991, had an earlier tree maturity than other trees in the block of the same age. Plants of this new variety were produced under orchard practices at Broetje Orchards and observed at this location from 1992 to 1997. Plants were also produced and observed at Columbia and Okanagan Nursery, Wenatchee, Washington.

Tests & Trials: Trials for 'Fiero' were conducted at the Pacific Agri-Food Research Centre, Agriculture and Agri-Food Canada, Summerland, B.C. from 2004 to 2006. The trials consisted of 12 trees of the candidate variety, 6 trees of 'Fuji BC2' and 14 trees of 'Royal Gala'. All trees were grafted on to M9 rootstock and planted in close proximity in Field 2 test blocks. The trees of 'Fiero' and 'Royal Gala' were planted in 1998 and the trees of 'Fuji BC2' were planted in 2000. Measured characteristics were based on a minimum of 10 measurements.
