(2) For the purposes of sub-paragraph (1)(a) and (c) plants shall be considered as having shed pollen or to be shedding pollen where, on 50 mm or more of the central axis or laterals of a panicle, the anthers have emerged from their glumes and have shed or are shedding pollen.
11.—(1) The provisions of this paragraph apply to a hybrid of rye.
(2) Subject to paragraph (3), the crop shall conform to the following standards as regards distances from neighbouring sources of pollen which may result in undesirable foreign pollination—

(ii)where male sterility is not used, a minimum distance of 600 metres, and
(b)for the production of CS seed, a minimum distance of 500 metres.
(3) Sub-paragraph (2) shall not apply if there is sufficient protection from any undesirable foreign pollination.

(a)in the case of a crop for the production of basic seed, one per 30 square metres, and
(b)subject to paragraph (6), in the case of a crop for the production of CS seed, 1 per 10 square metres.
(6) In an official UK field inspection or a UK field inspection carried out under official supervision the standard in sub-paragraph (5)(b) shall apply to the female component only.
(7) In the case of basic seed, where male sterility is used, the level of sterility of the male-sterile component shall be at least 98%.
(8) Where appropriate, CS seed shall be produced in mixed cultivation of a female male-sterile component with a male component which restores male fertility.
12.—(1) The provisions of this paragraph apply to a crop to produce a hybrid of barley, durum wheat, oats, self-pollinating triticale, spelt wheat or wheat.
(2) Subject to paragraph (3), the female component of the crop shall be at least 25 metres from a crop of any other variety of the same species except from a crop of the male component.
