Origin & Breeding History: 'Cupid' arose from the cross, 'Egbert Centre' and 'Kelleris 14', made in 1992 as part of the Fruit Breeding and Research Program of the Department of Plant Sciences, University of Saskatchewan, Saskatoon, Saskatchewan. Progeny was collected from the original cross, was stratified and container grown, then field planted on their own rootstock in the spring of 1994. Advanced selection status took place in 1999. Selection criteria included productivity, winter hardiness, extent of suckering, ease of fruit removal and fruit quality characteristics.

Tests & Trials: The tests and trials for 'Cupid' were planted in 2004 at the University of Saskatchewan, Horticulture Fields, Saskatoon, Saskatchewan. Forty bushes were planted in rows, spaced 1.5 metres apart in the row with a row spacing alternating between 3 and 4 metres. The data for the measured characteristics was collected during the 2009 and 2012 growing seasons. Measured characteristics were based on 30 measurements per variety per year.
