Variety used for comparison: 'Omega'
Summary: The lightsprout of 'Rumba' is ovoid in shape with medium to dense pubescence at the tip and base whereas it is spherical in shape with dense pubescence at the tip and base of the lightsprout for 'Omega'. The lightsprout base of 'Rumba' has a strong to very strong intensity of anthocyanin colouration whereas 'Omega' has a medium intensity of anthocyanin colouration at the base. The foliage structure of 'Rumba' is a leaf type (foliage closed, stems not, or hardly visible) whereas 'Omega' is an intermediate type (foliage half open, stems partly visible). The extent of the anthocyanin colouration is low and halfway up the stem for 'Rumba' whereas the extent of the anthocyanin colouration is medium and at the base only for 'Omega'. 'Rumba' has a taller plant height than 'Omega'. The extent of the anthocyanin colouration on the flower bud is absent or very low for 'Rumba' whereas it is medium to high for 'Omega'. The extent of the anthocyanin colouration on the inner side of the corolla is absent or very low for 'Rumba' whereas it is high for 'Omega'. The intensity of the anthocyanin colouration on the inner side of the corolla is absent or very weak for 'Rumba' whereas it is weak to medium for 'Omega'. The tubers of 'Rumba' are oval in shape whereas they are short oval in 'Omega'.
LIGHTSPROUT: medium size, ovoid, root tips few in numbers, short lateral shoots
LIGHTSPROUT BASE: strong to very strong intensity of anthocyanin colouration, with high proportion of blue in the anthocyanin colouration, medium to dense pubescence
LIGHTSPROUT TIP: large size in relation to base, intermediate to open habit, weak intensity of anthocyanin colouration, medium to dense pubescence
PLANT: foliage structure is a leaf type where foliage is closed and stems are not, or hardly visible, semi-upright growth habit, late maturity
STEM: low extent of anthocyanin colouration halfway up the stem
LEAF: small to medium outline, intermediate openness, medium green colour, absent or very low extent and absent or very weak intensity of anthocyanin colouration on the midrib of the upper side
SECOND PAIR OF LATERAL LEAFLETS: medium size, narrower than long width in relation to length
LEAFLETS: weak to medium presence of secondary leaflets, low frequency of coalescence of terminal and lateral leaflets, medium to strong waviness of margin, shallow to medium depth of veins, medium to glossy of upper side, no pubescence on blade at apical rosette
INFLORESCENCE: high to very high frequency per plant, medium to large size, absent or very low extent of anthocyanin colouration on peduncle
FLOWER BUD: extent of anthocyanin colouration is absent or very low
COROLLA: medium size, absent or very low extent and absent or very weak intensity of anthocyanin colouration on the inner side, with absent or low proportion of blue
TUBER: oval shape, medium yellow flesh
TUBER EYES: shallow depth
TUBER SKIN: light beige, yellow at base of eye, absent to weak anthocyanin colouration in reaction to light
Origin & Breeding History: The origin of 'Rumba' is the result of the cross made in 1995 between 'Bolesta' and 'Mira' in Böhlendorf (Mecklendburg-West Pomerania, Germany). Selection criteria were based on positive agronomic criteria.
Tests & Trials: Tests and trials for 'Rumba' 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.
