13.
(1)
Subject to sub-paragraph (2), it shall be determined, by way of a germination test, whether the seed attains the percentage of germination specified in column 2 of the following table for the appropriate category of seed—
Species | Minumum germination (% of pure seed, expressed as an integer) |
|---|---|
1 | 2 |
(a)Basic, CS, C1 and C2 seed of— (i)barley (ii)durum wheat (iii)oats (other than CS, C1 and C2 seed of oats officially classified as being of a naked oat type) (iv)spelt wheat (v)wheat | 85 |
(b)CS, C1 and C2 seed of oats officially classified as being of a naked oat type | 75 |
(c)Basic and CS seed of maize | 90 |
(d)Basic and CS seed of rye | 85 |
(e)Basic, CS, C1 and C2 seed of triticale | 80 |
(2)
Sub-paragraph (1) shall not apply to seed that has been subjected to a tetrazolium test carried out at an official testing station or a licensed seed testing station to establish the viability of the seed unless the result of the test casts doubt on whether it will satisfy the applicable germination standard set out in column 2 of the table set out in sub-paragraph (1).
14.
Sclerotia, or fragments of sclerotia, of ergot, shall not exceed the following in a sample of the weight specified in column 4 of Schedule 7, other than a sample of a hybrid of rye—
Category | Level (where applicable) | Sclerotia or fragments of sclerotia |
|---|---|---|
(a)Basic seed | (i)HVS level (ii)Minimum level | 0 1 |
(b)CS seed | Not applicable | 3 |
(c)C1 and C2 seed | (i)HVS level (ii)minimum level | 1 3 |
15.
(1)
In a sample of a hybrid of rye of a weight specified in column 4 of Schedule 7 sclerotia or fragments of sclerotia of ergot shall not exceed—
(a)
1 in the case of basic seed, and
(b)
subject to sub-paragraph (2) below, 4 in the case of CS seed.
(2)
Notwithstanding the provisions of sub-paragraph (1)(b), the presence of 5 sclerotia or fragments of sclerotia of ergot in a sample shall be deemed to be in conformity with the requirements of sub-paragraph (1) where a second sample of the same weight contains not more than 4 sclerotia or fragments of sclerotia.
16.
(1)
Subject to paragraph (2), the maximum moisture content of the seed shall not exceed 17% by weight.
(2)
A licensed seed testing station to which a regulation 11 application for the testing of an official sample of seed has been made (or the Secretary of State in a case where regulation 11(3) or (4) applies), may decide not to carry out a moisture test to determine whether the condition in paragraph (1) has been complied with if—
(a)
the official sample of the seed to be tested has already been subjected to a moisture test carried out by the licensed seed sampler who drew the official sample, and
(b)
the results of that test indicate that the maximum moisture content of the seed does not exceed 17% by weight.
