ORIGIN: Norchip was tested as ND5899-1 and released by North Dakota State University in 1968. The parentage is ND4731-1 (Norgleam x Antigo) x M5009-2 (a selection from the University of Manitoba). CHARACTERISTICS: Norchip has a determinate growth habit, medium-early maturity, medium-large plant size and tends to be upright. Stems are green without other pigmentation. Nodes are green, straight and not swollen. Leaves are medium in size, light green (pale at maturity) and closed. The terminal leaflets are large, lanceolate with truncate bases and asymmetrical lobes. Primary leaflets are large and tend to cup when plants are under stress. Petioles are green, flowers are white, anthers are orange and pollen is abundant and of fair quality. STRENGTHS & WEAKNESSES: Chip color is good to excellent at harvest and after long term storage. Tubers are moderately tolerant to common scab and potato flea beetle, but susceptible to late blight, Verticillium wilt, virus X, leaf roll and spindle tuber. Norchip is highly susceptible to early blight. Tubers develop growth cracks, off type and dumbbells when plants are stressed. |
