Variety used for comparison: 'Natascha'
Summary: The lightsprout of 'Francisca' is large with a broad cylindrical shape and many root tips whereas the lightsprout of 'Natascha' is medium in size with an ovoid shape and a medium number of root tips. The tip of the lightsprout of 'Francisca' has a closed habit and a medium to strong intensity of anthocyanin colouration whereas the tip of the lightsprout of 'Natascha' has an open habit and an absent or very weak to weak intensity of anthocyanin colouration. The pubescence of the base of the lightsprout is dense for 'Francisca' whereas it is sparse for 'Natascha'. The plant of 'Francisca' is shorter than that of 'Natascha'. The extent of anthocyanin colouration of the stem of 'Francisca' is medium along the entire stem whereas the extent is low and only halfway up the stem for 'Natascha'. The frequency of coalescence of the terminal and lateral leaflets is low for 'Francisca' whereas the frequency is absent or very low for 'Natascha'. The extent of anthocyanin colouration of the flower bud is medium for 'Francisca' whereas the extent is absent or very low for 'Natascha'. The tuber of 'Francisca' is short oval to oval in shape whereas the tuber of 'Natascha' is long oval in shape. In reaction to light, the tuber skin of 'Francisca' develops a strong intensity of anthocyanin colouration whereas the tuber skin of 'Natascha' develops a medium intensity of anthocyanin colouration.

Origin & Breeding History: The variety 'Francisca' originated from a cross made in 2000 between 'Marabel' as the femaile parent and the selection designated '95-012-4' as the male parent as part of a private breeding program at Saka Pflanzenzucht GmbH & Co. KG breeding station in Windeby, Schleswig-Holstein, Germany. The resultant seed was planted in the greenhouse in 2001 and from these, tubers were harvested and planted in the field during the spring of 2002. The variety was selected in 2002 for its agronomic characteristics and resistance to various diseases.
Tests & Trials: The comparative trial for 'Francisca' was conducted during the growing season of 2014 in Drummond, New Brunswick. The trial consisted of a single row with 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 of each variety. Mean differences were significant at the 5% probability level based on a paired Student's t-test.
