S M O R GA S B OR D THE S M O R GA S B OR D HISTORY • Parentage: Blazer Russet × Classic Russet • Developed by the Tri-State Breeding and Research Program, released in 2012 • PVP issued in 2014 KEY ATTRIBUTES • High early- and late-season yields • Nice tuber shape and appearance • Excellent fry color and culinary qualities • Resistant to external defects • Short to medium dormancy • Good specific gravity IRRIGATION • Available soil moisture should be maintained between 65 and 85 percent from full emergence until late bulking; reduce to 60 to 65 percent as vines start to senesce. Avoid excessive soil moisture from mid- to late bulking. STORAGE • Store at 47 to 48 degrees to avoid sugar development. • Dormancy length 30 to 40 days shorter than Russet Burbank, depending on storage temperature. Teton Russet had a dormancy length in 45-degree storage of about 105 days compared to 135 for Russet Burbank. • Significantly lower susceptibility to Fusarium dry rot than Russet Burbank WEED CONTROL • Use of Matrix in weed control may result in growth cracks. • Not affected by Metribuzin applied at recommended rates SEED PRODUCTION • Teton Russet seed has been primarily been grown in Idaho, Colorado and Montana, although more sources of seed should be available from the 2017 seed crop.
