Summary: The lightsprout of 'Marilyn' has a spherical shape while it is ovoid in 'Annabelle'. The lightsprout base of 'Marilyn' has strong intensity of anthocyanin colouration and dense pubescence while the lightsprout base of 'Annabelle' has medium intensity of anthocyanin and medium pubescence. The tip of the lightsprout of 'Marilyn' has medium intensity of anthocyanin colouration and medium pubescence while the tip of the lightsprout of 'Annabelle' has weak intensity of anthocyanin and dense pubescence. 'Marilyn' has a low extent of anthocyanin colouration at the base of the stem while 'Annabelle' has a medium extent along the whole stem. The leaf of 'Marilyn' has a large outline with a closed to intermediate openness and medium green colour while the leaf of 'Annabelle' is medium sized and open with a light green colour. 'Marilyn' has a medium to strong presence of secondary leaflets while it is weak in 'Annabelle'. The frequency of coalescence of the terminal and lateral leaflets in 'Marilyn' is absent or very low while it is high in 'Annabelle'. 'Marilyn' has a taller plant height than 'Annabelle'. The corolla of 'Marilyn' is small while it is medium sized in 'Annabelle'. 'Marilyn' has a tuber with medium depth eyes while they are shallow on the tuber of 'Annabelle'.

Origin & Breeding History: The origin of 'Marilyn' is the result of the cross made in 1995 between 'Nicola' and 'Pomfine' at HZPC Research, Metslawier, The Netherlands. The selection criteria included yield, internal and external tuber quality and resistances against different diseases and pests.
Tests & Trials: Tests and trials were conducted during the 2011 growing season in Drummond, New Brunswick. Plots consisted of 60 plants grown in a single row with a row length of 18.5 meters and a row spacing of 0.9 meters.
