Origin & Breeding History: The origin of 'Belvedere' (experimental designation KO 971021R) is the result of a cross made in 1994 between 'Solara' and KO 921928 at the Konst Research Station, Hoofdweg, Holland. Selection criteria included high tuber set, good tuber shape and uniformity, good size and dry matter content.

Tests & Trials: Tests and trials were conducted during the 2011 growing season in Drummond, New Brunswick. Plots consisted of 60 plants grown in a single row with a row length of 18.5 meters and a row spacing of 0.9 meters.
