Variety Description

Varieties used for comparison: 'Chieftain', 'Norland', 'Nordonna' and 'LaRouge'

Summary: 'DarkRed Chieftain' differs mainly from the reference varieties in plant foliage structure, plant height, time of maturity, waviness of margin of the terminal and lateral leaflets, anthocyanin colouration on the upper side of the leaf rachis, flower bud and corolla, inflorescence size, corolla colour and tuber skin colour. 'DarkRed Chieftain' has an intermediate foliage structure while 'Norland' has a leaf type structure and 'LaRouge' has a stem type structure. 'DarkRed Chieftain' is taller than 'Norland'. The time of maturity for 'DarkRed Chieftain' is later than the other reference varieties. 'DarkRed Chieftain' has stronger waviness of the leaf margin in comparison to the reference varieties. The anthocyanin colouration on the upper side of the leaf rachis, flower bud and corolla is stronger for 'DarkRed Chieftain' than the reference varieties. 'DarkRed Chieftain' has a smaller inflorescence than 'Chieftain', 'Norland' and 'Nordonna'. The inner side of the corolla is blue-violet for 'DarkRed Chieftain' while it is red-violet for 'Chieftain', 'Norland' and 'LaRouge'. 'DarkRed Chieftain' has a darker red tuber skin than the reference varieties.

TUBER FLESH: white, no secondary colour

LIGHT SPROUT: small, conical shape, many root tips, short lateral shoots

TIP: same size as base, closed to intermediate habit, moderate anthocyanin colouration, dense pubescence

Origin & Breeding History: 'DarkRed Chieftain' originated from the self pollination of the variety 'Chieftain' in 2002. The first clonal selection of 'Do02-21' took place in 2002. The selection criteria included skin colour and overall general appearance. The final selection took place in St-Ubalde in September 2006.

Tests & Trials: The trials for 'DarkRed Chieftain' were conducted in St-Ubalde, Quebec in 2007. All entries were planted in single-row plots. The trial had a total of 60 plants per variety and was divided between two replicates. The plots consisted of 4 rows x 6 metres with each row containing approximately 15 plants which were spaced 40 cm apart and row spacing of 91.5 cm. Measured characteristics were based on 10 measurements.
