Purpose and description
Enable an agent to identify Vigna radiata, assess the condition and reproductive potential of its plants and seeds, and choose appropriate cultivation, conservation or handling actions.
Vigna radiata, commonly called mung bean, is an annual leguminous plant in the family Fabaceae, domesticated in South Asia and cultivated primarily for its edible seeds and sprouts.
It can be Identify a plant or seed lot and flag evidence insufficient to distinguish similar pulses.; Compare development with documented expectations for the same cultivar and growing context.; Select a context-appropriate propagation or conservation pathway using identity and viability evidence.; Investigate stress, nodulation or suspected pest damage through targeted observations and tests.; Assess pod maturity and seed condition before harvesting or storage.; Route seed intended for sprouting or consumption to the relevant food-safety assessment..
Distinguishing features
Check reproductive structures against a botanical key that separates Vigna radiata from Vigna mungo and other similar Vigna species; record the characters supporting the determination.
Use the combination of leaf, flower, pod and seed characters rather than a common name or green seed coat alone to support identification.
Examine seed shape, surface and hilum together with pod characters when distinguishing mung bean from black gram and other small-seeded pulses.
Treat sprouts and dehulled or split seeds as identification-limited material requiring traceable parent seed or another validated identification method.
Separate species identity from cultivar identity: a seed colour, maturity class or commercial label does not by itself establish a distinct species.

Characteristics
- Taxonomic determination
- confirmed Vigna radiata | provisional Vigna radiata | unresolved Vigna | other taxon Prevents similar pulses or uncertain material from receiving species-specific interpretations without supporting evidence.
- Cultivar or accession
- Linked cultivar, landrace or germplasm accession record; unknown permitted Connects observed variation and growing responses to the biological material actually being assessed.
- Material and developmental state
- dry seed | imbibed seed | seedling | vegetative plant | flowering plant | pod-filling plant | mature plant | senescent plant Determines which identification characters, condition checks and actions are applicable.
- Diagnostic morphology
- Recorded leaf, flower, pod, seed and hilum character states using a cited identification key Makes identification reviewable and separates observed characters from assumed identity.
- Developmental timing
- days from a stated sowing or emergence date to flowering and pod maturity Supports comparison of crop development when cultivar and growing conditions are also known.
- Root-zone conditions
- temperature in °C, soil pH, and water-content measurement with method and unit Provides context for emergence, growth and stress observations without assuming universal cultivation thresholds.
- Nodulation assessment
- not assessed | no nodules observed | nodules observed | effectiveness investigated Distinguishes visible nodulation from evidence about the plant's nitrogen-fixing relationship.
- Health assessment
- no symptoms observed | symptomatic | pest observed | cause confirmed | unresolved Supports proportionate investigation and handling without converting symptoms into an unsupported diagnosis.
- Seed-lot germination
- % germination with test method, sample size, date and conditions Estimates propagation performance for a particular lot rather than assuming all apparently intact seeds are viable.
- Seed moisture content
- % with wet-basis or dry-basis convention, method and sampling date Helps interpret storage condition and handling needs for mature mung-bean seed.

Drafted structure
Bundle to layer to finding to question, as the second pass will find it: 5 bundles · 9 layers · 16 findings · 24 questions.
Identity and germplasm Establishes which biological material is being called Vigna radiata and how that determination can be checked.
Mung-bean names, seed appearance and cultivar labels can conceal uncertainty about species or accession identity.
Species determination
Separates taxonomic identification from commercial naming and appearance-based guesses.
Diagnostic evidence
Record the identification method, available organs and observed characters used to distinguish Vigna radiata from similar pulses.
- Which characters in a cited botanical key distinguish this material from Vigna mungo and other locally relevant Vigna species? definition
- Is the available material sufficient for identification, or does a sprout, split seed or incomplete specimen require additional evidence? boundary
Cultivar and origin
Connects species-level identity to the cultivar, accession or population under observation.
Traceable biological material
Record accession or cultivar claims, their evidence and the collection or multiplication history relevant to interpretation.
- Which supplier record, accession record or field collection supports the claimed cultivar or population identity? provenance
- Does this material represent a named cultivar, landrace, wild population or unresolved seed mixture? boundary
Development and reproduction Describes the progression from mung-bean seed through establishment, flowering and mature pods.
Identification, crop assessment and harvest decisions depend on developmental stage and variation within the observed plants.
Emergence and vegetative growth
Tracks establishment and subsequent plant development in a defined growing context.
Establishment performance
Distinguish laboratory germination, field emergence and seedling survival when assessing establishment.
- What fraction of sown mung-bean seeds emerged and survived to the stated assessment date? measurement
- Which seed-lot tests and field observations would distinguish poor viability from unsuitable sowing conditions or seedling damage? action
Flowering and pod development
Records reproductive timing, pod formation and the distribution of maturity across a plant or population.
Reproductive progress
Record flowering and pod stages without assuming that all plants or pods mature together.
- How many days after the stated sowing or emergence date did flowering and mature pods first occur? measurement
- What proportion of pods is filling, mature or already opened, and how does that distribution affect harvest timing? action
Growing conditions and health Connects mung-bean growth and symptoms to its environment, root symbiosis and observed biological pressures.
An agent needs contextual evidence to distinguish environmental stress, nutrient limitations and biological damage.
Environment and root symbiosis
Interprets root-zone conditions and nodulation for the actual cultivar and site.
Root function context
Record water, temperature and soil observations alongside nodulation evidence; keep nodule presence separate from demonstrated effectiveness.
- What root-zone temperature, moisture and soil pH were measured during establishment and any subsequent growth decline? measurement
- What observations or tests support effective nodulation, and what inoculation history is documented for this mung-bean material? provenance
Stress and biological damage
Captures symptoms and damage patterns while preserving uncertainty about cause.
Cause-supported health assessment
Separate symptoms such as leaf yellowing, wilting or damaged seeds from a confirmed pest, disease or environmental diagnosis.
- Which mung-bean organs are affected, at what developmental stage, and with what incidence and spatial distribution? measurement
- Which locally appropriate inspection or diagnostic test would resolve the leading explanations before treatment is selected? action
Seed condition and use Assesses harvested mung-bean seed as biological material with distinct propagation, conservation and food-use pathways.
Species identity, germination performance, storage condition and food-use suitability answer different questions and require separate evidence.
Harvest and storage condition
Records maturity and seed-lot condition through harvesting, drying and storage.
Seed-lot integrity
Track moisture, damaged seeds, insect evidence and storage exposure for a traceable lot.
- What are the measured seed moisture content and proportions of immature, broken or insect-damaged seeds? measurement
- Which drying and storage conditions has this lot experienced since harvest? provenance
Propagation and food-use boundaries
Matches a seed lot to its intended use and identifies the assessments owned by neighbouring models.
Intended-use evidence
Assess propagation through germination and identity evidence, and refer edible sprout or food production decisions to the corresponding handling and safety model.
- What germination test and identity evidence support using this lot for planting or germplasm conservation? measurement
- If this lot is intended for edible sprouts or other food uses, which treatment records and food-safety assessments must accompany the transfer? boundary
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.
