Origin & Breeding History: 'SOLHY017' (experimental designation 21HY5467) is a true hybrid potato originating from the cross between the female parent ‘PL0229' and the male parent ‘PL0055' conducted at the Agventure B.V. breeding station in Ressen, The Netherlands in 2021. Based on maturity, plant structure, tuber characteristics as well as disease resistance the resulting progeny was designated 21HY5467 in 2022. Hybrid seed production commenced in 2022.

Tests & Trials: The comparative trials for 'SOLHY017' were conducted in Sainte-Croix, Quebec during the 2023 and 2024 growing seasons. Seeds were germinated in a green house and after 4 weeks the plantlets were transferred to an outdoor canopy for 5 days for acclimatization. The plantlets were then transplanted in the field and irrigated daily for 2 weeks. The field trial consisted of 4 replicates with plots arranged in a RCB Design. Each plot was a 5-metre-long hilled row containing 25 plants spaced 20 cm apart. Rows were spaced 0.915 metres apart. Lightsprout characteristics were assessed on 20 tubers harvested from the comparative trial and observed approximately 3 months after storage at 4 degrees Celsius.
