The lightsprout tip of 'Prince' has a weak intensity of anthocyanin colouration whereas that of 'Shepody' has a medium to strong intensity of anthocyanin colouration. The plants of 'Prince' have an intermediate type foliage structure, where the foliage is half open and the stems are partly visible, while those of 'Shepody' have a leaf type foliage structure, where the foliage is closed and the stems are not, or hardly visible. The stem of 'Prince' has a medium to high extent of anthocyanin colouration whereas that of 'Shepody' has an absent or very low extent of anthocyanin colouration. The leaf of 'Prince' has a medium sized outline whereas that of 'Shepody' has a large outline. The upper side of the leaf of 'Prince' is dark green while that of Shepody' is light green. The midrib on the upper side of the leaf of 'Prince' has a high extent of anthocyanin colouration while that of 'Shepody' has an absent or very low extent of anthocyanin colouration. The plants of 'Prince' are taller than those of 'Shepody'. The inner side of the corolla of 'Prince' has a weak intensity of anthocyanin colouration while that of 'Shepody' has a medium to strong intensity of anthocyanin colouration. The plants of 'Prince' mature late in the season while those of 'Shepody' mature mid-season.

Origin & Breeding History: 'Prince' (experimental designation SW 08-1984) originated from a hybridization conducted at the Lantmannen Seed B.V. breeding station in Emmeloord, Netherlands in 2007. The cross was made between the varieties 'ARG 96-0738', as the female parent, and 'SW 98-2723', as the male parent. Seed from the cross was planted in a greenhouse in 2008. The resulting tubers were harvested and planted in the field in Emmeloord, Netherlands in the spring of 2009. The new variety was selected from these progeny in 2009 based on its agronomic characteristics and resistance to various diseases.

Tests & Trials: The comparative trial for 'Prince' was conducted by Global Agri Services Inc. in Central Blissville, New Brunswick during the 2022 growing season. The field trial consisted of a single, 22 metre long row per variety. Each row contained 70 plants spaced 0.3 metres apart with inter-row spacing of 1.1 metres. Measurements were taken from 10 plants, or 10 parts of plants, of each variety. The mean difference was significant at the 5% probability level based on a paired Student's t-test. Lightsprout characteristics were assessed on 10 tubers harvested from the comparative trial and observed approximately 2.5 to 3 months after sprouting was promoted by exposing the tubers to an external agent.
