Purpose and description
Enable an agent to recognise a potato tuber, assess its condition and suitability for an intended use, and identify what evidence is needed before handling, processing or planting it.
A potato is the starch-rich stem tuber of the cultivated plant Solanum tuberosum, a member of the nightshade family Solanaceae, used as food, an industrial feedstock and vegetative planting material.
It can be Identify and group tubers using anatomical observations and traceable cultivar evidence.; Inspect and sort potatoes by size, greening, sprouting, damage and deterioration.; Request representative sampling or laboratory analysis when appearance cannot settle suitability.; Compare a potato lot with a defined cooking or processing specification.; Review storage history and select handling actions against requirements for the intended use.; Route candidate seed tubers to planting-stock checks before recommending propagation..
Distinguishing features
A potato is a stem tuber with eyes that contain buds; this distinguishes its anatomy from the storage root of a sweet potato.
Identification should combine tuber anatomy with origin or taxonomic evidence; colour, shape and the common name alone do not establish identity.
The model follows the detached tuber and its condition, rather than the roots, foliage and life cycle of the whole potato plant.
A potato is heterogeneous biological material with skin, flesh and variable composition, rather than a pure chemical substance with one fixed purity or melting point.
An intact tuber retains its anatomical identity; isolated starch, flour and prepared dishes require neighbouring product models.
Scope
+ Tuber identity, cultivar attribution and distinction from other underground storage organs
+ Individual tuber and lot characteristics, including size, skin, flesh and defects
+ Composition and physical properties relevant to cooking, processing and propagation
+ Postharvest condition, storage history and deterioration
+ Evidence supporting allocation to food, processing or planting
- Whole potato plants, botanical taxonomy and breeding programmes
- Field cultivation systems, soil management and crop production operations
- Prepared dishes and transformed products such as chips, potato flour and isolated starch
- Sweet potatoes, yams and other distinct storage-root or tuber commodities
- Diagnosis and treatment of human illness or potato plant diseases
Characteristics
- Identity and cultivar attribution
- Taxon or cultivar reference, supporting evidence and attribution confidence Connects the tuber to expected traits without treating an unverified cultivar label as established identity.
- Tuber size and shape
- Mass in g; length and transverse dimensions in mm; shape description Supports grading, portioning and assessment of suitability for a particular processing line.
- Skin and flesh appearance
- Skin colour, flesh colour, skin texture and whether observations are external or from a cut sample Supports identification and defect assessment while distinguishing cultivar traits from condition changes.
- Dry matter content
- % by mass, with sampling and analytical method Helps assess likely cooking behaviour and processing yield.
- Reducing sugar content
- g/kg fresh mass, with analytes, method and sampling date Informs assessment of browning and suitability for high-temperature processing.
- Greening and sprouting
- Observed green area and location; sprout count and length in mm; inspection date Flags physiological changes requiring use-specific assessment without equating appearance with a chemical assay.
- Damage and deterioration
- Cuts, bruising, softening, shrivelling, lesions or decay; affected count or mass fraction Supports sorting and investigation of defects that affect storage and intended use.
- Glycoalkaloid assessment
- mg/kg with named analytes, tissue sampled, mass basis, laboratory method and uncertainty; unmeasured where unavailable Separates measured chemical evidence from visual warning signs and unsupported safety conclusions.
- Storage exposure history
- Time-linked temperature in °C, relative humidity in %, light exposure and treatment records Helps explain changes in sprouting, water loss and processing quality.
- Intended use and supporting status
- Table use, processing, planting, other or undecided; supporting specification or certification Prevents suitability for one use from being assumed to establish suitability for another.

Tuber identity and boundaries Establishes what counts as the potato being assessed and the evidence behind its identity.
The name potato can refer to a plant, a harvested tuber or food; decisions require an explicit material boundary.
Anatomical recognition
Recognises potato tubers through observable structures and supporting origin evidence.
Eyes and tuber form
Record eyes, skin and overall tuber form, including whether damage or preparation obscures identifying features.
- Are eyes and other tuber features observable, and what evidence supports identification as potato rather than sweet potato or yam? definition
- Has peeling, cutting or processing removed enough identifying structure that a prepared-product model is needed? boundary
Cultivar and lot attribution
Connects individual tubers to cultivar claims and the lot whose condition they may represent.
Identity evidence and lot membership
Distinguish documented cultivar identity from appearance-based guesses and define the assessed lot.
- What grower, supplier or planting-stock record supports the stated cultivar? provenance
- Does the assessed lot contain one cultivar and harvest history, or a mixture requiring separate assessment? boundary
Composition and use performance Relates measured tuber properties to cooking and industrial processing requirements.
Potatoes with similar appearances can differ in texture, browning behaviour and usable yield.
Solids and sugars
Captures composition measurements that help distinguish processing behaviour.
Measured processing properties
Record dry matter and reducing sugars with methods and sampling context rather than relying solely on cultivar expectations.
- What dry matter and reducing sugar results are available, on what mass basis and from which sample? measurement
- Were the results measured on this lot after its current storage period or inferred from a cultivar description? provenance
Cooking and processing response
Tests performance against a named preparation or processing use.
Use-specific performance
Keep cooking texture, disintegration and frying colour tied to the preparation conditions under which they were observed.
- Under what cooking or frying procedure were texture, disintegration and colour assessed? measurement
- Does the observed performance meet the intended use specification, or should the lot be assessed for a different use? action
Postharvest physiology and condition Tracks physiological change, mechanical damage and deterioration after harvest.
A harvested potato remains living tissue whose condition changes with time, exposure and handling.
Dormancy, sprouting and water loss
Assesses visible growth and loss of firmness alongside storage history.
Physiological condition
Record sprout development, firmness and shrivelling without inferring dormancy or viability from appearance alone.
- What sprout lengths, firmness observations or measured mass losses describe the current tubers? measurement
- What harvest date, storage conditions and sprout-suppression treatments are documented? provenance
Skin integrity and internal defects
Separates surface inspection from evidence requiring cut samples or further investigation.
Damage and decay distribution
Record cuts, bruising, lesions, decay and internal defects with their extent and inspection method; keep causal diagnosis separate.
- Which defects are visible externally, and which were found only by cutting a sample? measurement
- How should affected tubers be sorted or referred for investigation under the lot's intended-use criteria? action
Use eligibility and routing Determines which evidence is needed before allocating tubers to food, processing or planting.
Visible quality, chemical assessment and planting-stock eligibility answer different questions and must remain distinguishable.
Food-use evidence
Connects warning signs, analytical results and treatment records to applicable food-use criteria.
Greening and chemical uncertainty
Record greening and sprouting as observations, not quantitative estimates of glycoalkaloids, and identify unresolved evidence before a food-use decision.
- What greening or sprouting is present, and are any glycoalkaloid measurements linked to the affected tissue? measurement
- Which applicable food-use criteria and treatment restrictions must be checked before accepting or rejecting this lot? action
Planting-stock eligibility
Distinguishes a tuber's capacity to sprout from evidence that it is suitable planting material.
Seed-tuber status
Record seed-stock certification, cultivar traceability, health evidence and treatment history when propagation is intended.
- What certification, health testing and treatment records support use of these tubers as planting stock? provenance
- What additional planting-stock checks are required beyond observing that the tubers can sprout? action
Evidence and external alignment What the world already says about this thing, gathered so the model can be checked against it.
A model that cannot be lined up against existing standards, identifiers and practice cannot be adopted by anyone who already uses them.
