Origin & Breeding History: 'Lady Terra' (experimental designation CMK2005-062-026) originated from the cross between 'Lady Olympia' as the female parent and CMK1998-803-002 as the male parent, conducted at the C. Meijer breeding station in Rilland, Netherlands in 2004. One of the resulting progeny was selected and designated CMK2005-062-026 in 2006 based on tuber shape, tuber flesh colour, yield and disease resistance.

Tests & Trials: The comparative trial for 'Lady Terra' was conducted by Global Agri Services Inc. in Central Blissville, New Brunswick during the 2023 growing season. The field trial consisted of a single 15.2 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. 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.
