Interpretive Summary:

Technical Abstract: Prolonged cold storage at temperature below 45°F often results in off color chips resulting from enhanced sugar accumulation. The objective of this study was to identify advanced public breeding lines that maintain good quality processing (light colored chips) after prolonged storage at contrasting storage temperature. Chip processing quality of public breeding lines was compared against several named check varieties throughout seven months of storage. After seven months of storage, nine of the thirty-one clones examined provided good quality chips processed directly from 42°F storage. Eleven more clones provided acceptable chip color following 7 month of storage at 45°F. Considerable cost savings could be achieved with storage at reduced temperature storage (<45°F) through decreased shrinkage, lower incidence of disease pressure, and decreased need for sprout inhibition.
