The proportion of blue in the anthocyanin colouration at the base of the lightsprout is absent to medium in 'Erika' whereas it is high in 'Agria'. The lightsprout tip of 'Erika' has an intermediate habit, has dense pubescence and a medium intensity of anthocyanin colouration on the tip. The lightsprout tip of 'Agria' has an closed habit, sparse pubescence and a very strong intensity of anthocyanin colouration on the tip. 'Erika' has small to medium leaves with intermediate openness whereas 'Agria' leaves are large and are intermediate to open. The plants of 'Erika' are shorter than those of 'Agria'. The frequency of inflorescences per plant for 'Erika' is absent or very low whereas it is high in 'Agria'. The tuber skin colour of 'Erika' is yellow whereas it is light beige in 'Agria'.

Origin & Breeding History: The origin of 'Erika' is the result of the cross made in 1997 between 'Marabel' as the female parent and 'AR 88-156' as the male parent at the Niederösterreichische Saatbaugenossenschaft (N.Ö.S.) breeding station in Meires, Austria. Selection criteria were negative mass selection agronomic characteristics and resistance to various diseases.

Tests & Trials: Tests and trials for 'Erika' were conducted during the 2012 growing season in Drummond, New Brunswick. Each plot per variety consisted of 60 plants grown in a single row with a row length of 18.5 metres and a row spacing of 0.9 metres between rows. Plants were spaced 0.30 metres apart.
