Entries Retained from the 2012 Trial Currently in the Tri-State Trial

Harvested fall of 2012 Held at 48°F until December 18 Stored at 44°F until analysis

Seven clones were retained from the 2012 Tri-State Trial into the 2013 Trial (A0012-5, A0073-2, A03921-2, A05052-3TE, A06003-3TE, A06084-1TE, and AO03123-2). When averaged across states, A03921-2 produced the lightest fries (50.6 ref units) and the uniformity of fry color was better for all clones relative to RB and Ranger. A06084-1TE had the shortest dormancy with the longest sprouts (9.5″), while A05052-3TE had the shortest average sprout length (1″), indicating significantly longer dormancy than either of the checks (Russet Burbank and Ranger Russet).
