Biological status of accession
The coding scheme proposed can be used at 3 different levels of detail: either by using the general codes (in boldface) such as 100, 200, 300, 400 or by using the more specific codes such as 110, 120 etc.
| Code | Term | Description |
|---|---|---|
| 100 | Wild | |
| 110 | Natural | |
| 120 | Semi-natural/wild | |
| 130 | Semi-natural/sown | |
| 200 | Weedy | |
| 300 | Traditional cultivar/landrace | |
| 400 | Breeding/research material | |
| 410 | Breeder's line | |
| 411 | Synthetic population | |
| 412 | Hybrid | |
| 413 | Founder stock/base population | |
| 414 | Inbred line (parent of hybrid cultivar) | |
| 415 | Segregating population | |
| 416 | Clonal selection | |
| 420 | Genetic stock | |
| 421 | Mutant (e.g. induced/insertion mutants, tilling populations) | |
| 422 | Cytogenetic stocks (e.g. chromosome addition/substitution, aneuploids, amphiploids) | |
| 423 | Other genetic stocks (e.g. mapping populations) | |
| 500 | Advanced or improved cultivar (conventional breeding methods) | |
