Seed coat pattern
The different shapes and localization of the pigments observed on the seed testa form the basis for this classification into various patterns. In the following descriptions, refer to Figures 3 and 4 for each part of seed described
| Code | Term | Description |
|---|---|---|
| 0 | No pattern , Group A | |
| 1 | Pattern around eye only, Group B | |
| 2 | Eye distinct with few specks on body, Group C1 | |
| 3 | Eye distinct with many specks on body, Group C2 | |
| 4 | Eye distinct with blotches on < 50% of body, Group D1 | |
| 5 | Eye distinct with blotches on >50% of body, Group D2 | |
| 6 | Eye linked to other parts of pattern, blotches in hilar region (more developed towards micropyle), some specks may be present, Group E1 | |
| 7 | Eye linked to other parts of pattern, blotch covering hilar region and front side, some specks may be present, Group E2 | |
| 8 | Eye linked to other parts of pattern, blotch covering hilar region, back, front and keel, specks present on rest of body, Group E3 | |
| 9 | Eye linked to other parts of pattern, blotch in hilar region, body has bands radiating from hilar region, Group E4 | |
| 10 | Eye linked to. other parts of pattern, blotch in hilar region, body has bands oriented radially and transversely, Group E5 | |
| 11 | Body sparsely mottled, Group F1 | |
| 12 | Body moderately mottled, some joined to form a blotch, Group F2 | |
| 13 | Body intensely mottled, seed background is almost hidden, Group F3 |
