2013 Tri-State Trial Longterm storage

Entries Retained from the 2013 Trial Currently in the Regional Trial

Harvested fall of 2013 Held at 48°F until December 21 Stored at 44°F until analysis

Three clones were retained from the 2013 Tri-State Trial into the 2014 Trial ( A0073-2, A03141-6 and AOR06070-1KF). When averaged across states, A0073-2 produced the lightest fries (44.0 ref units) and the uniformity of fry color was better for all clones relative to RB and Ranger. All entries and the check cultivars Ranger Russet and Russet Burbank had sprout lengths that averaged between 3.2 and 4.0 inches.
