Origin & Breeding History: 'Torino' (experimental designation T3537/2) originated from a cross conducted between 'Cornado', as the female parent, and 'Rooster', as the male parent, in the Teagasc breeding program in Carlow, Ireland in 1999. Seed from the cross was grown in a greenhouse in 2000 with resulting tubers planted in the field at the Teagasc Breeding Station in Carlow, Ireland in 2001. T3537/2 was selected in 2001 based on maturity, disease resistance, yield, tuber skin texture and tuber skin and flesh colour.

Tests & Trials: The comparative trial for 'Torino' was conducted by Global Agri Services Inc. during the 2021 growing season in Central Blissville, New Brunswick. The field trial consisted of a single, 20 metre long row per variety. Each row contained 65 plants spaced 0.3 metres apart with an inter-row spacing of 1.1 metres. 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.
