Variety used for comparison: 'Yukon Gold'
Summary: The lightsprout of 'Montreal' is large with an ovoid shape and sparse pubescence at the base whereas the lightsprout of 'Yukon Gold' is small with a spherical shape and dense pubescence at the base. The tip of the lightsprout of 'Montreal' has dense pubescence whereas it has sparse pubescence on 'Yukon Gold'. The plant of 'Montreal' has a semi-upright growth habit whereas that of 'Yukon Gold' has an upright growth habit. The leaflet from the second pair of lateral leaflets of 'Montreal' is as broad as it is long whereas the leaflet from the second pair of lateral leaflets of 'Yukon Gold' is narrower than it is long. The plant of 'Montreal' is taller than that of 'Yukon Gold'. The anthocyanin colouration on the inner side of the corolla of 'Montreal' is of absent or very low extent and absent or very weak intensity whereas the anthocyanin colouration on the inner side of the corolla of 'Yukon Gold' is of high extent and weak intensity. In reaction to light, the tuber skin of 'Montreal' develops a weak intensity of anthocyanin colouration whereas the tuber skin of 'Yukon Gold' develops none or a very weak intensity of anthocyanin colouration.

Origin & Breeding History: The variety 'Montreal' originated from a cross made in 1997 between 'Amora' as the female parent and 'Amalia' as the male parent as part of a private breeding program at the Aardappelkweekbedrift Boerhave B.V. breeding facility in Elburg, The Netherlands. The resultant seed was planted in the greenhouse in Elburg in 1998 and from these, tubers were harvested and planted in the field during the spring of 1999. The variety was selected for its agronomic characteristics and resistance to various diseases.
Tests & Trials: The comparative trial for 'Montreal' was conducted during the growing season of 2014 in Drummond, New Brunswick. The trial consisted of a single row with 60 plants spaced 0.3 metres apart for each variety. The distance between rows within the trial was 0.9 metres. Observations and measurements were taken from 10 plants of each variety. Mean differences were significant at the 5% probability level based on a paired Student's t-test.
