Origin & Breeding History: In 2003, 30 wild rose ecotypes were collected on Prince Edward Island. Stem sections were field propagated and data was collected from 2005 to 2011. One ecotype, 'S26', was selected in 2011 based on rose hip yield, unique chemical composition and mechanical harvestability.
Tests & Trials: Tests and trials were conducted in Charlottetown, Prince Edward Island during the 2005 to 2012 growing seasons. There were 3 replicates of each variety consisting of 5 plants per replicate. Plants were spaced 4 metres apart between rows and 1 metre apart between plants in the rows. The trial was originally planted in 2005. Measured characteristics were based on 45 measurements per ecotype for plant height and plant width, and 30 measurements per ecotype for fruit length and fruit width.
