Origin & Breeding History: 'Markies' originated from the cross of 'Fianna' and 'Agria', made in Ulrum, the Netherlands in 1984. The selection process was based on negative agronomic criteria.

Tests & Trials: Trials for 'Markies' were conducted in Central Blissville, New Brunswick in 2008. All entries were planted in single-row plots. Plots consisted of rows 22 metres long spaced 91 cm apart with 30 cm in row spacing between plants. Measured characteristics were based on 10 measurements. Colour determinations were made using the 1986 RHS colour chart.
