Origin & Breeding History: 'Tilbury' (experimental designation G06TT376008) originated from the cross between ‘Gunda' and 'Jenny' conducted at the Germicopa breeding station in Châteauneuf-du-Faou, France in 2005. Lines were advanced from 2006 to 2009 based on visual impression. One line was designated ‘G06TT376008' in 2006. The variety was further assessed from 2010 to 2012 based on pest resistance, yield, processing quality, storability, and visual impression, and designated ‘Tilbury' in 2010.

Tests & Trials: The comparative trial for 'Tilbury' 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.
