Varieties used for comparison: 'Atlantic' and 'Snowden'
Summary: In relation to the base, the lightsprout tip of 'Manistee' is small whereas the lightsprout tip in relation to the base for 'Atlantic' is large and for 'Snowden' is medium size. The intensity of the anthocyanin colouration of the lightsprout tip is weak for 'Manistee' whereas the intensity of the anthocyanin colouration of the lightsprout tip is medium for 'Atlantic' and absent or very weak for 'Snowden'. From the second pair of leaflets, the leaflet of 'Manistee' is large whereas the leaflet of 'Atlantic' is medium to large and the leaflet of 'Snowden' is medium sized. The depth of the veins of the leaflet is shallow for 'Manistee' whereas the depth of the veins of the leaflet is deep for 'Atlantic' and medium depth for 'Snowden'. The inner side of the corolla of 'Manistee' has medium intensity of anthocyanin colouration whereas the corolla of 'Atlantic' has a weak to medium intensity of anthocyanin colouration and the corolla of 'Snowden' has an absent or very weak intensity of anthocyanin colouration.

TUBER EYE: medium depth, yellow at base
TUBER SKIN: light beige, develops strong intensity of anthocyanin colouration in reaction to light
Origin & Breeding History: 'Manistee' originated from a cross conducted in 1999 between 'Snowden' and 'MSH098-2', as part of a breeding program at Michigan State University in East Lansing Michigan. 'Manistee' was selected in 2000 for its positive agronomic characteristics.
Tests & Trials: The comparative trial for 'Manistee' was conducted by Global Agri Services Inc. during the growing season of 2016 in Drummond, New Brunswick. The trial consisted of a single, 19.5 metre long row containing 65 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, or 10 parts of plants, of each variety.
