Teton Russet (A0008-1TE)

Parentage – Blazer Russet x Classic Russet^1,2,3

Breeder – Originated from a hybridization at the USDA Agricultural Research Service, Aberdeen, Idaho in 2000^1,2; released for production by the Pacific Northwest Potato Variety Development Program (comprised of the USDA Agricultural Research Service and the Agricultural Experiment Stations of Idaho, Oregon and Washington) in 2011^1,4

Maturity – Early-season^1,2,3,4

Usage – Primarily grown for fresh market and processing; excellent fry color^1,2,3,4

Plant –Small-medium, partially compact bush, semi-erect structure; stems with weakly prominent stem wings and strong anthocyanin pigmentated coloration in lower half¹

Leaves –Large, partially closed, moderate pubescence¹; dark green with weakly wavy margins; weak anthocyanin pigmentation on the upper side of the leaf midrib (main vein) and petioles; terminal leaflets are broadly ovate with a tapered tip and obtuse base; two to five pairs (average of 3.5) of medium ovate, tapered tip primary leaflets with heart-shaped bases; six to ten pairs of (average of 6.7) secondary and tertiary leaflets¹

Flowers – semi-star shape, medium size, white with yellowish-orange loose shaped anthers; limited pollen production; limited frequency of flower clusters (one to five) per plant¹

Tubers – Oblong to long, medium reddish-brown, russet skinned^1,2,3; average of fourteen evenly distributed, shallow eyes with medium prominent eyebrows per tuber; white flesh; sprouts have a blue-violet pigmentation at base and tip; approximately five to six tubers produced per plant¹; medium-high specific gravity; medium dormancy period^1,3

Strengths – High US # 1 yields with high vitamin C and protein content; resistant to common scab and Fusarium Dry Rot; moderately resistant to net necrosis^1,3,4; low incidence of growth cracks and secondary growth^1,3; tolerant of Metribuzin³

Weaknesses – Susceptible to Verticillium wilt, black dot, Columbia root- knot nematode, early blight, late blight, corky ringspot, potato leafroll virus, soft rot, potato virus X and Y¹ and shatter bruise^1,3
