Interpretive Summary: Technical Abstract: The objective of this study was to identify advanced public breeding lines that maintain quality chip and fry processing during storage at contrasting storage temperature. Prolonged cold storage at temperatures below 45°F often results in off color chip or fries resulting from enhanced sugar accumulation. 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. Chip and french fry quality of public breeding lines was compared against several named check varieties throughout storage. After seven months of storage, twenty-nine of the thirty-nine chip clones provided good quality chips processed directly from 42°F storage. However, only eleven of the 48 russet clones provided french fry quality similar to the industry check, Russet Burbank, following 7 month of storage at 45°F. The poor russet quality in 2018 may be attributed to cold stressed field conditions prior to harvest. This 2018 field experiment will be repeated in 2019. |
