The fruit of 'HW113' has medium anthocyanin colouration around the stone whereas that of 'Harblaze' has absent of very weak anthocyanin colouration around the stone. The stone of 'HW113' has strong anthocyanin colouration and is dark brown whereas that of 'Harblaze' has weak anthocyanin colouration and is light brown.

Origin & Breeding History: 'HW113' originated from a traditional cross pollination between the variety 'S3800' and an unknown male parent. The cross was conducted at Agriculture and Agri-Food Canada in Harrow, Ontario in 1988 after which time the plants were moved to Vineland Research Station in 1993 for further evaluation. 'HW113' was selected as a five year old tree for its fruit size, fruit taste, harvest maturity window and disease tolerance.

Tests & Trials: The trial for 'HW113' 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 4 trees each of the candidate and reference variety. Trees were grown on 'Bailey' rootstock and young trees were planted in rows with approximately 3 metre spacing between trees in 2003 at the Vineland Research Station. One tree of the candidate died and was replanted in 2009. 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 30, 2013 for 'HW113' and August 21, 2013 for 'Harblaze'. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
