(2) The crop must have at least 99.99% (by number) species purity.
(3) Other than a hybrid, the minimum varietal purity of seed is—
(a)99.95% for basic seed;
(b)99.9% for C1 seed;
(c)99.7% for C2 seed.
(4) In the case of C1 and C2 the seed must have 99% by weight analytical purity.
Additional requirements for barley, wheat, durum wheat and spelt wheat
17. In the case of barley, wheat, durum wheat and spelt wheat—
(a)the maximum number of wild oats in a crop is 7 per hectare.
(b)the maximum percentage by number of loose smut infection in seed is—
(i)0.1% for basic seed;
(ii)0.2% for C1 and C2 seed.

18. The number of seeds from other plant species in a sample of 1000g must not exceed the following.
Seed of other species
| Category of seed sampled | All other plant species (including species specified in columns 3 to 6) | Other cereal species | All plant species other than cereals | Wild oats or darnel | Wild radish, corn cockle, sterile brome or couch |
|---|---|---|---|---|---|
(a) Only in respect of wild radish and corn cockle. | |||||
| Basic seed | 1 | 0 | 1 | 0 | 0(a) |
| C1 | 2 | 1 | 1 | 0 | 1 |
| C2 | 4 | 3 | 2 | 0 | 1 |
Ergot and sclerotia
19. In a sample of 1000g—
