Bannock Russet (A81473-2)

Percentage– A75175-1 x A75188-3^1,2

Breeder– Selected from a cross made in Aberdeen, ID in 1981^1,2; released by the USDA Agricultural Research Service and the Agricultural Experiment Stations of Idaho, Oregon, and Washington in 1999^1,2.3

Maturity– Late-season^1,2,3

Usage– French fry and other frozen product processing; excellent fresh market qualities¹

Plant– Medium to large, upright with semi-closed canopy; medium-thick, green, non-pigmented stems with straight-edged single wings¹

Leaves– Medium green, open, moderately pubescence; terminal leaflets are medium, ovate, moderately asymmetrical with heart-shaped tips and rounded bases; three to five pairs of medium, narrowly ovate primary leaflets^1,2; zero to four pairs (avg. 2.4) of secondary leaflets and zero to six pairs (avg. 1.0) of tertiary leaflets; green petioles¹

Flowers– Multiple, medium size, star shape, white with yellow-orange anthers^1,2; one to four flower clusters per plant; no field pollen or berry production¹

Tubers– Oblong to long, brown heavily russeted skin; white flesh; approximately twelve shallow eyes per tuber concentrated near the apical end with non-prominent eyebrows¹; medium tuber dormancy; high specific gravity^1,2  

Strengths– Produces high quality U.S. No. 1 yields with reduced nitrogen levels as compared to growing Russet Burbank^1,2,3; resistant to potato virus Y, Verticillium wilt, common scab, and potato leafroll net necrosis; moderate resistance to early blight and soft rot¹; moderately resistant to internal and external defects such as growth cracks, secondary growth and blackspot bruise^1,2; no metribuzin sensitivity¹

Weaknesses– Susceptible to late blight (foliar and tuber), corky ringspot, potato leafroll virus, potato virus X, Fusarium dry rot and Columbia root knot nematode^1,3; susceptible to shatter bruise and small yields of large tubers, however, use of correct cultural practices will correct these issues^1,2,3
