Origin & Breeding History: 'CN 99 113 1' originated from a cross between the varieties 'Dali' and 'Eden' in 1997 at the Station de Recherche du Comité Nord, Bretteville-du-Grand-Caux, France. From the resulting progeny, 'CN 99 113 1' was selected in 2000 based on negative mass selection for agronomic characteristics, dry matter content, cooking quality and frying quality, industrial end use and disease resistances.

Tests & Trials: The comparative test and trial for 'CN 99 113 1' was conducted by Global Agri Services Inc. during the growing season of 2017 in Drummond, New Brunswick. The trial consisted of a single, 21.2 metre long row containing 70 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. The mean difference was significant at the 5% probability level based on a paired Student's t-test.
