Variety Description

Variety used for comparison: 'Mondial'

Summary: The proportion of blue anthocyanin colouration at the base of the lightsprout of 'Bridget' is high whereas it is low to medium for 'Mondial'. The pubescence of the tip of the lightsprout of 'Bridget' is medium to dense whereas it is absent or very sparse for 'Mondial'. The presence of secondary leaflets on the leaves of 'Bridget' is strong whereas it is medium for 'Mondial'. The plants of 'Bridget' are taller than those of 'Mondial'. The extent of anthocyanin colouration on the inner side of the flower corolla of 'Bridget' is medium whereas it is absent or very low for 'Mondial'. The anthocyanin colouration on the inner side of the flower corolla of 'Bridget' is of medium intensity whereas it is absent or very weak for 'Mondial'. The plants of 'Bridget' mature mid to late season whereas those of 'Mondial' are very late maturing.

Origin & Breeding History: 'Bridget' originated from a cross between the varieties 'Sinora' and 'Agnes' conducted in 1999 at the Aardappelveredelingsbedrijf Jalving B.V. breeding station in Wezup, Netherlands. From the resulting progeny, 'Bridget' was selected in 2001. Selection was based on negative mass selection and disease resistances.

Tests & Trials: The comparative test and trial for 'Bridget' 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.
