Variety Description

Variety used for comparison: 'Markies'

Summary: The lightsprout of 'Papapura' is small with a strong intensity of anthocyanin colouration and a low to medium proportion of blue at the base whereas it is medium sized with a very strong intensity of anthocyanin colouration and a high proportion of blue at the base of the lightsprout on 'Markies'. The foliage structure of the plants of 'Papapura' is an intermediate type (foliage half open, stems partly visible) whereas 'Markies' has a leaf type (foliage closed, stems not, or hardly visible). There is a high extent of anthocyanin colouration on the stem of 'Papapura' whereas it is medium on 'Markies'. The leaf of 'Papapura' has a small outline size and is open whereas they are medium sized with intermediate openness on 'Markies'. There is medium extent and intensity of anthocyanin colouration along the midrib of the upper side of the leaf of 'Papapura' whereas it is absent or very low with absent or very weak intensity on 'Markies'. 'Papapura' has strong to very strong waviness of the leaflet margins whereas it is weak on 'Markies'. The plants of 'Papapura' are taller than those of 'Markies'. The inflorescence of 'Papapura' is small with medium to strong intensity of anthocyanin colouration on the inner side of the corolla whereas it is medium sized on 'Markies' with absent or very weak intensity of anthocyanin colouration. The tubers of 'Papapura' are long oval to long with dark yellow flesh whereas those of 'Markies' are oval with medium yellow flesh.

Origin & Breeding History: The origin of 'Papapura' is the result of the cross made in 1994 between 'ARD 84-21304' as the female parent and 'ARD 88-13901' as the male parent at the Agrico Research breeding station in Emmeloord, The Netherlands. Selection criteria were negative mass selection agronomic characteristics and resistance to various diseases.

Tests & Trials: Tests and trials for 'Papapura' 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.
