Variety used for comparison: 'Fontane'

Summary: The lightsprout of ‘Palace' is large, has medium to many root tips, and short lateral shoots while that of ‘Fontane' is medium in size, has very few to few root tips, and very short lateral shoots. The base of the lightsprout of ‘Palace' is broad cylindrical, has a strong intensity of anthocyanin colouration, and dense pubescence while that of ‘Fontane' is globose, has a very strong intensity of anthocyanin colouration, and a medium density of pubescence. The apex of the lightsprout of ‘Palace' has an intermediate habit, a weak intensity of anthocyanin colouration, and dense pubescence while that of ‘Fontane' has a closed habit, a very strong intensity of anthocyanin colouration, and a sparse to medium density of pubescence. The plants of ‘Palace' are taller than those of ‘Fontane'. The stem of ‘Palace' has a low extent of anthocyanin colouration while that of ‘Fontane' has a high extent of anthocyanin colouration. The leaf of ‘Palace' is large to very large with many secondary leaflets while that of ‘Fontane' is medium in size with a medium number of secondary leaflets. The inner side of the corolla of ‘Palace' has a very high extent of strong intensity anthocyanin colouration while that of ‘Fontane' has an absent or very low extent of weak intensity anthocyanin colouration.

Origin & Breeding History: 'Palace' (experimental designation AR 08-4241) originated from the cross between ‘AR 01-3350' as the female parent and 'ADD 93-20902' as the male parent, conducted at the Agrico Research B. V. breeding station in Bant, Netherlands in 2007. One of the resulting progeny was designated AR 08-4241 in 2009 based on tuber shape, tuber number, tuber appearance, and disease resistance.

Tests & Trials: The comparative trial for 'Palace' was conducted by Global Agri Services Inc. in Central Blissville, New Brunswick during the 2024 growing season. The field trial consisted of a single 14.86 metre long row per variety. Rows were spaced 1.1 metres apart with each row containing 65 plants spaced 0.23 metres apart. 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.
