Origin & Breeding History: 'Noblesse' originated from a cross between the selection 'RZD 95-1618', as the female parent, and the variety 'Victoria', as the male parent, conducted in 2002, at HZPC Holland B.V. in Metslawier, Netherlands. From the resulting progeny, 'Noblesse' was selected in 2003 based on yield, internal and external tuber quality as well as disease and insect resistances.

Tests & Trials: The comparative test and trial for 'Noblesse' was conducted during the growing season of 2017 in Drummond, New Brunswick. The trial consisted of a single, 21.2 metre long row containing 70 plants spaced 0.3 metres apart for each variety. The distance between rows within the trial was 0.9 metres. Observations and 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.
