Prioritize strong storage candidates
Identify varieties or lots with stronger inherent potential to retain processing quality during extended storage.
Potato storage and processing-quality advisory
Better storage and breeding decisions through biochemical insight
AgriSacUSA provides scientific advisory support for evaluating potato storability, retaining processing quality, and applying biochemical-marker information to storage management and variety development.
The industry challenge
Storage decisions must balance quality, dormancy, shrinkage, and disease risk
Potato storage managers routinely monitor fry color and sugar levels, but those measurements largely describe quality at the time of testing. They do not always provide a forward-looking assessment of how a field, lot, or variety may perform during storage.
Biochemical-marker information can add another layer of evidence by helping characterize inherent cold-induced sweetening risk and the likely ability of potatoes to retain acceptable processing quality under different storage conditions.
Application 1
Support for growers and storage managers
Marker-informed assessment can help organize lots and varieties according to expected storage behavior and processing-quality risk.
Match storage duration to risk
Support decisions about which lots may be better suited for intermediate storage and earlier processing.
Recognize higher-risk material
Flag lots that may warrant shorter storage, closer monitoring, or adjusted management.
Potential decision areas
- Storage-duration planning for different fields, lots, and varieties
- Prioritization of lots for long-, medium-, or short-term use
- Interpretation of processing-quality risk alongside fry color and sugar data
- Planning of storage temperature, reconditioning, and monitoring strategies
Biochemical markers are decision-support tools. Final storage recommendations should consider variety, crop history, field environment, maturity, disease status, and direct quality measurements.
Evidence over time
Marker classes designed to reflect stable biological differences
The biochemical-marker approach was developed from research across genetically diverse potato material and evaluated over multiple years. The underlying concept is that stable biochemical characteristics can help distinguish potatoes with stronger, intermediate, or weaker resistance to cold-induced sweetening.
This creates an opportunity to complement repeated end-point quality testing with information about the biological potential of a variety or clone.
Use biochemical insight to move from simply measuring current quality toward anticipating storage behavior and directing management attention where it is most needed.

Application 2
Support for potato breeding and variety development
Breeding programs evaluate very large populations and discard most material during the earliest generations. Better parent choice and earlier selection can improve the efficiency of that process.
Parent selection
Use biochemical-marker information to help choose parents more likely to produce progeny with desirable storage and processing characteristics.
Early-generation screening
Identify promising progeny sooner and reduce the number of low-potential clones carried through costly multi-year evaluations.
Focused advancement
Concentrate storage trials, field testing, and processing-quality evaluation on material with stronger supporting evidence.
Time and cost efficiency
Improve selection efficiency, reduce avoidable testing, and potentially shorten the path to new variety development.
Published and industry-facing work
A practical concept communicated to both scientists and the potato industry
The biochemical-marker work has been presented through peer-reviewed research and an industry article in Spudman. The industry article explained potential uses in storage management, parent selection, early-generation screening, and national variety-development programs.
