46 POTATO GROWER | NOVEMBER 2017 S M O R GA S B OR D THE S M O R GA S B OR D HISTORY • Developed by Tri-State Breeding & Research Program, released in 2012 • PVP issued in 2012 • Parentage: AWN86514-2 × A86102-6 KEY ATTRIBUTES • High marketable yields with few defects • Excellent fresh culinary quality • Exceptional processing following long- term storage at 42 degrees • Strong resistance to late blight, Verticillium wilt, black dot and pink rot • Moderate resistance to PVY and early blight CHARACTERISTICS • Medium to late vine maturity • Oblong, lightly russeted tubers with intermediate eye depth and white flesh • High yield potential, with typically high percentage of U.S. No. 1 tubers • Average specific gravity between 1.095 and 1.103 in Northwest • Tuber dormancy about 40 days shorter than Russet Burbank • Suitable for both fresh pack and French fry processing. CULTURAL TIPS • Requires 10 percent less nitrogen than Russet Burbank • Late-season over-fertilization or over- irrigation leads to increased incidence of shatter bruise • Seed size: 1.5 to 3 ounces • Planting depth: 8 inches from top of seed piece to top of hill • Irrigate similar to Russet Burbank. Maintain ASM between 65 and 85 percent from full emergence until late bulking; reduce to 60 to 65 percent as vines start to senesce. PRODUCTION • Palisade Russet seed is currently only grown in Idaho. Check www.pvmi.org for a full list of seed growers. T his month we take a look at Palisade Russet, a dual-purpose russet that was introduced in 2012. Palisade Russet has displayed low sugar end occurrence and outstanding disease resistance that makes it a solid choice for organic production. The cultivar's typically high specific gravity makes it more suitable for areas where gravities range on the lower side. A big thank-you goes out to Jeanne Debons at the Potato Variety Management Institute for her help in gathering information. 46 POTATO GROWER | NOVEMBER 2017
