Potato

Variety Description

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'.

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.
