Norland (ND2906-1R)

Parentage – Redkote x ND626^1,2,3,4

Breeder – Released by the Horticultural Department at North Dakota Agricultural College in 1957^1,2; Red Norland is a darker red line selection of Norland observed in 1965⁴; Dark Red Norland, New Red Norland, Super Red Norland and Red Norland Strain 72 are line selections of Red Norland; Red Norland and Dark Red Norland are more readily grown than Norland⁵

Maturity – Early season^1,2,3,4

Usage – Primarily used for fresh market^1,2,3,4; very good for boiling, frying, chipping (best at harvest); fair for baking^3,4

Plant – Medium to large size, spreading foliage with medium-thick, prominently angled stems^1,2,3,4

Leaves – Dark green, glossy, slightly cupped, medium to large size; medium size, broadly ovate and slightly asymmetrical terminal leaflets; three pairs of primary leaflets with slightly pubescent petioles; numerous secondary and tertiary leaflets^1,3

Flowers – Few, medium to large size, purple with a spreading habit; medium to large orange anthers with large green stigma^1,4

Tubers – Oblong, slightly flattened, uniform size with smooth red (intensity can vary) skin; evenly distributed shallow eyes with medium deep eyebrows; white flesh^1,2,3; low to intermediate specific gravity^1,2,4

Strengths – Produces high numbers of US#1 grade tubers early in the growing season; seldom produces irregular shaped, knobby or growth cracked tubers; low level of tuber internal defects like hollow heart, internal necrosis and vascular discoloration observed; moderately resistant to common scab, potato wart, and Rhizoctonia^1,2,3,4; highly resistant to potato virus A³

Weaknesses – Sensitive to drought; tubers susceptible to skinning and bruising if harvested before mature; susceptible to black leg, Fusarium dry rot, early and late blight, potato leafroll virus, Phoma rot, seed-piece decay, Verticillium wilt, potato virus X and Y; highly susceptible to silver scurf^2,3,4; red skin color fades as tubers mature^2,4
