Origin & Breeding History: 'Hanareum' arose from the cross of 'Niitaka' and 'Chuwhang' made in the spring of 1988 at the National Horticulture Research Institute, Rural Development Adminstration, Suwon, Republic of Korea. It was planted in the field in the spring of 1996 and first selected for its fruit quality, large size and attractive skin colour. From 1997 to 2001, it was tested at 9 sites in regional adaptability tests. The final selection of 'Hanareum' was completed in 2001.

Tests & Trials: Tests and trials were conducted at the Agriculture & Agri-Food Canada, Pacific Agri-Food Research Centre, Summerland, British Columbia during the 2013 to 2016 growing seasons. Plots consisted of a minimum of 10 trees of each variety with a spacing of 1 meter between trees within the row and 3.5 meters between the rows of trees. The trees were grafted on 'Old Home' rootstock and were originally established during the 2011 growing season. Measured characteristics were based on a minimum of 10 measurements per variety.
