Varieties used for comparison: 'Norland' and 'Sangre'
Summary: 'BC Reds' has no anthocyanin in the stem and petiole while 'Norland' and 'Sangre' have weak to medium anthocyanin. 'BC Reds' has absent to very weak levels of coalescence in terminal and lateral leaflets whereas 'Sangre' has moderate to high levels of coalescence. Tubers of 'BC Reds' are oval to oblong whereas those of the reference varieties are round. The light sprout of 'BC Reds' is larger than that of 'Sangre'. The base of the light sprout of 'BC Reds' has less anthocyanin and less pubescence than the reference varieties. The tip of the light sprout of 'BC Reds' has less anthocyanin and more pubescence than that of 'Sangre'.

TIP: smaller than base, open habit, anthocyanin weak to moderate, moderate pubescence.
Origin & Breeding History: 'BC Reds' originated from a single plant discovered in a field in Chetwynd, British Columbia, by the applicant in 1991. The field had been planted with 'Norgold Russet' and one row of an unknown red potato variety planted in between the rows. The plant of the new variety was noticed to produce large, long, narrow tubers. The variety was propagated over the next four years and found to be uniform and stable.
Tests & Trials: Trials for 'BC Reds' were conducted in Drummond, New Brunswick in 2005. A block design was used with four replicates per variety. All entries were planted in single-row plots and each entry had one replicate per block. Plots consisted of rows 5.5 metres long and between row spacing of 91 cm. Measured characteristics were based on 10 measurements. Colour determinations were made using the 1986 RHS colour chart.
