‘Alpine Russet’ is a high yielding, medium to late maturing potato variety with oblong tubers, light russet skin and good processing quality following long-term storage. It has moderately high specific gravity, resistances to sugar ends, tuber malformations and most internal and external defects. It is notable for a tuber dormancy most like that of ‘Russet Burbank’, making it an excellent candidate for long-term storage, with processing characteristics superior to that of ‘Russet Burbank’. ‘Alpine Russet’ produces oblong tubers with medium thickness and light russet skin. The eyes are shallow in depth and intermediate in number and are predominately apical. Tuber set is low, and tuber size is medium large.

‘Alpine Russet’ has moderate resistance to scab and Verticillium wilt. It has a high early yield with large percentage of US No.1 tubers. Its weaknesses include a light russet skin and susceptibility to PVY.

‘Clearwater Russet’ is medium-late maturing, with oblong-long tubers that have medium russet skin. Tubers exhibit excellent fry color out of storage and their attractiveness make this variety suitable for both processing and fresh market usage. It has high specific gravity and is resistant to sugar ends as well as most internal and external tuber defects. This potato variety is notable for having a higher protein content than those of standard potato varieties, with 38% greater concentration than ‘Russet Burbank’.

‘Clearwater Russet’ produces oblong tubers with brown, medium-heavy russet skin. The eyes are shallow in depth and intermediate in number and are evenly distributed. Tuber set is low, and tuber size is medium. Total yields for ‘Clearwater Russet’ ranged from about 92% to 97% of ‘Ranger Russet’ and 88% to 105% of ‘Russet Burbank’ in 26 yield trials conducted in eastern Idaho, central and western Idaho, Washington and Oregon. U.S. No. 1 yields for ‘Clearwater Russet’ ranged from 105% to 111% of Ranger Russet yields in Idaho and Oregon but only 86% of ‘Ranger Russet’ yields in Washington. By comparison, U.S. No. 1 yields for ‘Clearwater Russet’ were 47%, 25%, 51% and 20% higher than ‘Russet Burbank’ in eastern Idaho, western and central Idaho, Oregon and Washington, respectively.

‘Gem Russet’ is a medium to late maturing, medium to high yielding potato variety with long tuber type and medium russet skin. It is useful for both the fresh and processing markets with high specific gravity; excellent fry color from 45°F storage and will often fry acceptably following 40°F storage.

Strengths include excellent tuber shape and appearance, high grade out, long dormancy, high solids and good fry color. Weaknesses include late emergence and mediocre yields in some environments and susceptibility to PVY. Although highly susceptible to PVY, the ‘Gem Russet’ variety shows only mild symptoms that can be masked in many field situations. Because of mild symptom expression, it is sometimes considered a symptomless carrier of PVY. ‘Gem Russet’ is also susceptible to early dying and late blight. It has moderate resistance to scab.

‘GemStar Russet’ is a dual-purpose potato variety suitable for processing and fresh-pack usage. It has high U.S. No. 1 yields with extremely attractive tubers having few external defects and higher concentrations of Vitamin C and protein than other potato cultivars. ‘GemStar Russet’ is cold-sweetening resistant making it exceptional for use in processing. It is resistant to PVX, common and powdery scab and soft rot, and has moderate resistance to Verticillium wilt, net necrosis and corky ringspot. ‘GemStar Russet’ is notable for its tolerance to water stress. It is very susceptible to PVY and dry rot, and late-season hollow heart can be problematic as well. A release article for ‘GemStar Russet’ was published in the American Journal of Potato Research in 2006, volume 83.

The plant has a semi-erect vine that matures in the middle of the season and produces oblong tubers with heavily russeted skin. The eyes are intermediate in number and not well distributed. Tuber set is low, with average size typically medium, although large tubers are common with medium dormancy. ‘GemStar Russet’ produced higher total yields than Russet Burbank in eastern Idaho, but slightly lower yields in the longer season areas of western Idaho and Oregon. In 27 trials in Idaho, Oregon and Washington, ‘GemStar Russet’ produces tubers with higher specific gravity than those of ‘Russet Burbank’ and produced much better fry color out of both 40- and 45-degrees Fahrenheit storage.

‘GemStar Russet’ has demonstrated less susceptibility to growth cracks and secondary growth, but slightly more susceptibility to shatter bruise and much greater susceptibility to hollow heart than Russet Burbank. Blackspot bruise susceptibility is slightly less or like that of ‘Russet Burbank’.

‘Ivory Crisp’ is an early chipping potato variety with a high specific gravity and medium to high yield. It has good cold chipping potential and long-term storage capability. With spreading vines that mature in mid-season, it produces numerous white flowers and netted round tubers with white skin with eyes that are intermediate in number and not well distributed. Tuber set is medium as is the tuber size.

‘Ivory Crisp’ has similar yields to ‘Atlantic’ in Idaho and produced tubers with similar specific gravity and slightly lower tuber solids than ‘Atlantic’. It produced better chip color both out of 40°F and 50°F storage It is less susceptible to hollow heart than ‘Atlantic’ with other internal and external quality characteristics fairly similar.

‘Ivory Crisp’ is generally like ‘Atlantic’ with respect to disease resistance, except that Atlantic is immune to PVX, while ‘Ivory Crisp’ is susceptible. ‘Atlantic’ is also somewhat more resistant to PVY infection.

‘Summit Russet’ as late maturity and is a high yield potato variety. It was selected for superior tuber quality and has shown good performance for both French fry processing and table stock market characteristics. Tubers of this variety have produced consistent and high tuber specific gravity and excellent fry color following storage. It was intended to replace ‘Russet Burbank’ and/or ‘Russet Norkotah’ produced for storage. Summit Russet matures late in the season and produces tubers typically long in shape and somewhat flattened, with moderately russeted skin. The skin russeting has usually been very uniform from stem to bud end. The eyes have shown a tendency to be relatively low in number and not well distributed. Tuber number is typically low and has longer dormancy, 140 days when stored at 45°F, as compared to 145 days for ‘Russet Burbank’.

In comparative trials in Idaho, Oregon, and Washington Summit Russet has produced total tuber yields like or less than Russet Burbank but it produced higher yields and percentages of U.S. No. 1 tubers than ‘Russet Burbank’ in all regions of the Northwest. In quality evaluations, tubers had much higher tuber solids (specific gravity) than did those of Russet Burbank. It also produced better fry color following storage at both 40°F and 45°F.

‘Summit Russet’ has shown less susceptibility than ‘Russet Burbank’ to all major external and internal defect problems. Tubers have shown good resistance to growth cracks and second growth, moderate resistance to shatter and blackspot bruise, and moderate susceptibility to hollow heart. On average, it has shown less hollow heart than Russet Burbank. It has demonstrated more resistance to Verticillium wilt, foliar and tuber early blight, foliar and tuber late blight and tuber net necrosis than Russet Burbank.

‘Yukon Gem’ is a round-oblong, yellow-fleshed potato variety that is remarkably like its parent, ‘Yukon Gold’. ‘Yukon Gem’ is higher yielding (12% higher in Idaho) than ‘Yukon Gold’ and is resistant to PVY, common scab, tuber blight (early and late), net necrosis, blackspot and shatter bruise. It is moderately resistant to dry rot and foliar late blight. Its resistances make it a good candidate for organic production. It also makes acceptable chips, but its lower specific gravity may limit its use for this purpose.

‘Yukon Gem’ has an erect, medium vine that matures relatively early in the season. It produces medium red-purple flowers that tend to abort. It produces round to oval, light yellow skin with pink splash around the eyes. The eyes are intermediate in depth and number and are evenly distributed.
