Variety used for comparison: 'Bintje'
Summary: The intensity of anthocyanin colouration of the base of the lightsprout of 'Amanda' is weak whereas the intensity is very strong for 'Bintje'. The proportion of blue in the anthocyanin colouration of the base of the lightsprout of 'Amanda' is absent or low whereas the proportion of blue is high for 'Bintje'. The pubescence of the tip of the lightsprout of 'Amanda' is absent or very sparse whereas the pubescence is of medium density for 'Bintje'. The anthocyanin colouration of the stem and the upper side of the leaf midrib of 'Amanda' is absent whereas for 'Bintje', the anthocyanin colouration is of low extent and weak intensity. The frequency of coalescence of the terminal and lateral leaflets of 'Amanda' is absent or very low whereas the frequency of coalescence is low for 'Bintje'. The degree of waviness of the leaflet margin of 'Amanda' is weak to medium whereas the waviness is absent or very weak for 'Bintje'. The extent of anthocyanin colouration of the peduncle of 'Amanda' is absent or very low whereas the extent is medium for 'Bintje'. The extent of anthocyanin colouration of the flower bud of 'Amanda' is absent or very low whereas the extent is high for 'Bintje'.

Origin & Breeding History: 'Amanda' originated from the Saka Pflanzenzucht private breeding program in Windeby, Schleswig-Holstein, Germany. It is the result of a hybridization conducted in 1999 between the selection designated '94-709-2' and the variety 'Innovator'. The seed from the cross was planted in a greenhouse in 2000 and the resulting tubers were planted in a field during the spring of 2000. From these, 'Amanda' was selected in 2001 for its agronomic characteristics and resistance to various diseases.
Tests & Trials: The comparative trial for 'Amanda' 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.
