Variety Description

Variety used for comparison: 'Allians'

Summary: The lightsprout of 'Sissi' have short lateral shoots whereas they are of medium in length for 'Allians'. The intensity of the anthocyanin colouration at the base of the lightsprout for 'Sissi' is strong with the proportion of blue as absent or low whereas the intensity is weak with a medium proportion of blue for 'Allians'. At the tip of the lightsprout, the intensity of the anthocyanin colouration is strong for 'Sissi' whereas it is weak for 'Allians'. The leaves are light green for 'Sissi' whereas they are medium green for 'Allians'. The extent of the anthocyanin colouration on the flower bud is low for 'Sissi' whereas the extent is absent or very low in 'Allians'. The extent of the anthocyanin colouration on the inner side of the corolla is high for 'Sissi' whereas it is absent or very low for 'Allians'. The intensity of the anthocyanin colouration on the inner side of the corolla is medium for 'Sissi' whereas it is absent or very weak for 'Allians'. The plants of 'Sissi' are late maturing whereas those of 'Allians' mature mid to late season. The tubers of 'Sissi' have an oval to long oval shape whereas they have a long oval shape in 'Allians'. The anthocyanin colouration of the tuber skin in reaction to light in 'Sissi' is strong whereas it is weak in 'Allians'.

INFLORESCENCE: medium to high frequency per plant, medium size, absent or very low extent of anthocyanin colouration on peduncle
FLOWER BUD: low extent of anthocyanin colouration
COROLLA medium to large size, high extent and medium intensity of anthocyanin colouration on the inner side, with absent or low proportion of blue

TUBER: oval to long-oval shape, medium to dark yellow flesh

TUBER SKIN: yellow, yellow at base of eye, strong anthocyanin colouration in reaction to light

Origin & Breeding History: The origin of 'Sissi' is the result of the cross made in 1998 between 'Exempla' as the female parent and 'Laura' as the male parent at the Bavaria-Saat BGB Ges.mbH breeding program in Oberarnbach, Germany. Selection criteria included early maturity, high tuber count, good tuber shape and uniformity, and good size.

Tests & Trials: Tests and trials for 'Sissi' were conducted during the 2012 growing season in Drummond, New Brunswick. Each plot per variety consisted of 60 plants grown in a single row with a row length of 18.5 metres and a row spacing of 0.9 metres between rows. Plants were spaced 0.30 metres apart.
