The plants of ‘Sinatra' have many to very many inflorescences, and mature late in the season while those of ‘Atlantic' have few to a medium number of inflorescences, and mature mid-season. The leaf of ‘Sinatra' is small to medium in size with very few to few secondary leaflets while that of ‘Atlantic' is large with a medium number of secondary leaflets. The flower bud of ‘Sinatra' has an absent or very weak intensity of anthocyanin colouration while that of ‘Atlantic' has a strong intensity of anthocyanin colouration. The inner side of the corolla of ‘Sinatra' has an absent or very low extent of absent or very weak intensity anthocyanin colouration while that of ‘Atlantic' has a high extent of medium intensity anthocyanin colouration. The tuber of ‘Sinatra' has a shallow depth of eyes while that of ‘Atlantic' has a medium depth of eyes.

Origin & Breeding History: 'Sinatra' (experimental designation 11-216-1) originated from the cross between '02-412-2' as the female parent and 'Crisps4all' as the male parent, conducted at the SaKa Pflanzenzucht GmbH & Co. KG breeding station in Windeby, Germany in 2010. One of the resulting progeny was designated 11-216-1 in 2012 based on yield, tuber number, tuber appearance, depth of tuber eyes, plant height, and disease resistance.

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