Varieties used for comparison: 'Shepody' and 'Ranger Russet'

Summary: The base of the lightsprout of 'Crop 37' has a high proportion of blue in the anthocyanin colouration whereas the reference varieties have an absent or low proportion of blue in the anthocyanin colouration at the base of the lightsprout. The stem of 'Crop 37' has a low to medium extent of anthocyanin colouration whereas the stems of the reference varieties have an absent or very low extent of anthocyanin colouration. The intensity of anthocyanin colouration on the inner side of the corolla is strong for 'Crop 37' whereas the intensity of anthocyanin colouration on the inner side of the corolla is weak to medium for 'Shepody' and medium for 'Ranger Russet'. The shape of the tuber of 'Crop 37' is oval to long-oval whereas the shape of the tuber of 'Shepody' is long oval to long and the shape of the tuber of 'Ranger Russet' is long oval.

Origin & Breeding History: 'Crop 37' originated from a cross between '345/7' and 'Fianna' conducted in 1990 by the New Zealand Institute for Crop & Food Research, in Pukekohe, New Zealand. 'Crop 37' went through 10 growing cycles and was selected for its positive agronomic characteristics.

Tests & Trials: The comparative trial for 'Crop 37' 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.
