The lightsprout of 'Jennifer' has a medium number of root tips whereas the lightsprout of 'Sifra' has few root tips. The anthocyanin colouration of the stem is absent for 'Jennifer' whereas the extent of anthocyanin colouration is low for 'Sifra'. The leaflet of 'Jennifer' has a medium degree of waviness of the margin whereas the leaflet of 'Sifra' has weak waviness of the margin. The extent of anthocyanin colouration of the flower bud and peduncle of 'Jennifer' is absent or very low whereas the extent is low to medium for 'Sifra'.

COROLLA (INNER SIDE): absent or very low extent of anthocyanin colouration, absent or very weak intensity of anthocyanin colouration, absent or low proportion of blue in anthocyanin colouration

TUBER: short oval shape, cream coloured flesh
TUBER EYE: shallow, yellow at base
TUBER SKIN: yellow, develops medium to strong intensity of anthocyanin colouration in reaction to light

Origin & Breeding History: 'Jennifer' originated from a cross conducted at D. Biemond B.V. in Eenrum, Netherlands, in 2001, between the varieties 'Voyager', as the female parent, and 'BIE 94-890', as the male parent. The resulting seedlings were tested in the Netherlands and at different testing locations abroad. 'Jennifer' was selected in 2002 for its yield, internal and external quality, and resistance to different diseases and pests.

Tests & Trials: The comparative trial for 'Jennifer' was conducted during the growing season of 2015 in Drummond, New Brunswick. The trial consisted of a single, 18.5 metre long row containing 60 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. Mean differences were significant at the 5% probability level based on a paired Student's t-test.
