Origin & Breeding History: 'Bonnata KWS' (experimental designation KWS 05-656) originated from a cross between 'Bernadette', as the female parent, and RZ 95-6643, as the male parent, conducted in 2005 at the KWS Potato B.V. breeding station in Noord Oost Polder, Netherlands. In 2005, the seed resulting from the cross was sown in the greenhouse. The resulting tubers were harvested and planted in the field in 2005 in Noord Oost Polder, Netherlands. 'Bonnata KWS' was selected in 2005 based on negative mass selection for agronomic characteristics and disease resistance.

Tests & Trials: The comparative trial for 'Bonnata KWS' was conducted by Global Agri Services Inc. during the 2019 growing season in Drummond, New Brunswick. The trial consisted of a single, 21 metre long row per variety. Each row contained 70 plants spaced 0.3 metres apart with an inter-row spacing of 0.9 metres.
