Payette Russet (A02507-2LB)

Parentage – EGAO9702-2 x GemStar Russet^1,2,3

Breeder – Cross conducted at the University of Idaho Aberdeen Research and Extension Center in 2002^1,2; released by the USDA-ARS and the Agricultural experiment Stations of Idaho, Oregon and Washington in 2015¹

Maturity – Late^1,2,3

Usage – Excellent for processing^1,3; some fresh-pack application¹

Plant – Erect to semi-erect, closed foliage making stems barely visible; stems have no pigmentation and moderately prominent wings^1,2

Leaves –Closed silhouette, sparse leaf hairs, medium green color with non-pigmentated petioles^1,2; narrow, ovate terminal leaflets with a pointed tips, heart-shaped bases and medium margin waviness; three to five pairs (avg. 4.1) of ovate primary leaflets with sharp points and blunt bases; three to nine pairs (avg. 6.5) of secondary and tertiary leaflets¹

Flowers – Medium to large, white^1,2, pentagonal shape with pear-shaped, orange anthers; one to seven (avg. 4.2) flower stalks per plant; berry production only occurs if a male-fertile variety is in close proximity¹

Tubers – Oblong, medium size, russeted, reddish brown skin^1,2,3; average of eighteen medium deep eyes per tuber; white flesh^1,2; long tuber dormancy; high specific gravity^1,3; higher tuber protein content than standard russet varieties³

Strengths – Produce higher U.S. No. 1 yields; known for cold-sweetening resistance and low acrylamide formation; consistently produces lighter fry color than industry standards; extreme resistance to potato virus Y (all strains); resistant to common scab, late blight (foliar and tuber); moderately resistant to Verticillium wilt, hollow heart, early blight, corky ringspot, secondary growth and growth cracks^1,3

Weaknesses – Late emergence and development can occur when planted early; can produce oversized tubers; moderately susceptible to potato virus X, soft rot and tuber net necrosis; susceptible to Fusarium dry rot, potato leafroll virus, shatter bruise^1,3, potato mop-top virus, internal brown spot, bacterial ring rot and weight loss in storage¹
