Origin & Breeding History: 'Jeannette' originated from the cross between 'Charlotte' and 'Franceline' conducted at la Station de Recherche du Comité Nord in Bretteville du Grand Caux, France, in 1990. The resulting seed was sown and the resulting tubers field planted in Bretteville du Grand Caux, France, in 1998. One of the progeny, designated as 'Jeannette', was identified in 1998. Selection criteria was based on negative mass selection for agronomic characteristics and disease resistance.

Tests & Trials: The comparative trial for 'Jeannette' was conducted by Global Agri Services Inc. during the 2018 growing season in Drummond, New Brunswick. The trial consisted of a single, 21 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.
