Origin & Breeding History: 'HW109' originated from a traditional cross pollination between the varieties 'HW106' and 'A334N'. The cross was conducted at Agriculture and Agri-Food Canada in Harrow, Ontario in 1987 after which time the plants were moved to Vineland Research Station in 1991 for further evaluation. 'HW109' was selected as a four year old tree for its fruit size, fruit colour, fruit taste, harvest maturity window and disease tolerance.

Tests & Trials: The trial for 'HW109' was conducted in an orchard during the spring/summer of 2013, at Vineland Research and Innovations Centre Inc., in Vineland, Ontario. The trial included a total of 3 trees of the candidate variety and 4 trees of the reference variety. Trees were grown on 'Bailey' rootstock and young trees were planted in rows with approximately 3 metre spacing between trees in 1997 at the Vineland Research Station. Additional trees of the candidate were observed at a local commercial orchard. Observations and measurements were taken from 10 plant parts, with flower characteristics observed on May 7, 2013, leaf characteristics on July 8, 2013 and fruit characteristics on August 21, 2013. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
