• ORIGIN:
    Norland was tested as ND2908-1R and released by the North Dakota
    Agricultural College in 1957. The parentage is Redkote xND626.
    Several darker red-skinned strains of Norland have been selected
    since its release.




     CHARACTERISTICS:
    Norland is widely adapted, early maturing and has a determinate type of growth.
    Plants are medium large and spreading with stems that are medium-thick and
    prominently angled. Nodes are slightly swollen and green with green internodes
    and waved wings. Leaves are medium to large, slightly closed and medium green.
    Leaflets are ovate, acute lobed and asymmetrical. Petioles are green.
    Flowers are purple with medium-large orange anthers with abundant pollen.



    Tubers:
    Are oblong, smooth, slightly flattened, medium red with shallow eyes. Specific
    gravity is low to intermediate and yields are low to intermediate.



     
     STRENGTHS & WEAKNESSES:
    Tubers are excellent for boiling and frying and fair for baking.
    The variety seldom produces off-type, knobby or growth-cracked
    tubers and it is not susceptible to internal defects. It is tolerant to common
    scab but is susceptible to infection by the common viruses, early blight, late
    blight and air pollution injury. Red skin color decreases after tubers mature.  







  • Purpose -- fresh market, boiling (“new reds”), salads, also frying
  • Growth Type -- determinate
  • Maturity -- early season, 70-90 days after planting
  • Dormancy -- short period
  • Emergence -- rapid
  • Vine -- medium, spreading and slightly erect, and open
  • Leaves -- medium to large, medium to dark green, slightly closed
  • Flowers -- few, medium sized, dark red-purple
  • Roots -- shallow to medium, 12 to 15 inches
  • Tubers -- oval to round, slightly flattened, uniform; smooth, slightly reddish skin; more reddish skin with strains Red Norland and Dark Red Norland
  • Set -- very variable; 6 to 12 first set observed in Nebraska variety trials
  • Eyes -- shallow to medium; moderate in number; evenly distributed
  • Specific Gravity -- low (1.060-1.070), good for boiling
  • Sugar -- medium-high
  • External Defects -- none; resists growth cracking, secondary growths and mis-shaped growth
  • Internal Defects -- none; resists hollow heart, internal necrosis and vascular discoloration
  • Yields -- low to medium with high proportion of US#1 grade
  • Disease susceptibility -- (vine) most viruses, early dying (Vert. wilt), black leg, and blights; (tuber) seed decay (dry rot) and silver scurf
  • Disease tolerance -- (vine) stem and stolon canker; (tuber) common scab and net necrosis
  • Bruising -- prone to skinning, shatter and internal brown spot (IBS)
  • Herbicide Sensitivity -- susceptible to metribuzin injury
  • Other -- fair competitor against weeds; sensitive to drought; sensitive to air pollution
