Paragraph 8 Special conditions for maize
For hybrid varieties the plant shall conform to the known characteristics of the parental lines.
Notwithstanding the provisions of paragraph 3 of this part of this Schedule, in respect of maize, the cultural condition of the field must also permit sufficient checks of the varietal identity and the varietal purity of the inbred lines and of the emasculation of plants for the production of seeds of hybrid varieties.
Unless there is adequate protection against undesirable pollen there should be a distance of at least 200 metres from neighbouring crops of other varieties or inbred lines or from crops of the same variety or inbred line of a lower category.
The percentage by number of recognisable off-types shall not exceed, for the production of—
| Basic Seed … | 0.1 |
| Certified Seed of hybrid varieties … | 0.2 |
| Certified Seed of open pollinated varieties … | 0.5 |
With regard to the emasculation of plants for the production of Certified Seed of hybrid varieties, the observed percentage of plants of the female parent ascertained to have emitted pollen shall not exceed one at any one official examination and shall not exceed two in all the official examinations carried out on the crop;
In the production of Certified Seed of hybrid varieties, all the parent plants shall flower sufficiently simultaneously.
