Origin & Breeding History: 'Saint Valentine' arose from the cross of 'Kerr's Easy Pick' and 'Cacanski Rubin', made in 1992 as part of the Fruit Breeding and Research Program of the Department of Plant Sciences, University of Saskatchewan, Saskatoon, Saskatchewan. 'Kerr's Easy Pick' was an unreleased selection derived from Prunus fruticosa x Prunus cerasus hybrids that were interbred for several generations over 40 years. 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 'Saint Valentine' 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 growing season.
