# The Beet Seeds Regulations 1993, Paragraph 6: Isolation distances


The minimum distances from neighbouring pollen sources shall be:
Crop
Minimum distance
The above distances can be disregarded if there is sufficient protection from any undesirable foreign pollinator. No isolation is necessary between seed crops using the same pollinator.
The ploidy of both seed-bearing and pollen-shedding components of seed-producing crops is to be established by reference to the Common Catalogue or National List.
If this information is not included for any variety, the ploidy is to be regarded as unknown, and a minimum isolation distance of 600 metres is required.
1 For the production of Basic Seed: from any pollen sources of the genus Beta
1,000 m
2 For the production of Certified Seed:
(a) of sugar beet:
from any pollen sources of the genus Beta not included below
1,000 m
the intended pollinator or one of the intended pollinators being diploid, from tetraploid sugar beet pollen sources
600 m
the intended pollinator being exclusively tetraploid, from diploid sugar beet pollen sources
600 m
from sugar beet pollen sources, the ploidy of which is unknown
600 m
the intended pollinator or one of the intended pollinators being diploid, from diploid sugar beet pollen sources
300 m
the intended pollinator being exclusively tetraploid, from tetraploid sugar beet pollen sources
300 m
between two sugar beet seed production fields in which male sterility is not used
300 m
(b) of fodder beet:
from any pollen sources of the genus Beta not included below
1,000 m
the intended pollinator or one of the pollinators being diploid, from tetraploid fodder beet pollen sources
600 m
the intended pollinator being exclusively tetraploid, from diploid fodder beet pollen sources
600 m
from fodder beet pollen sources, the ploidy of which is unknown
600 m
the intended pollinator or one of the pollinators being diploid, from diploid fodder beet pollen sources
300 m
the intended pollinator being exclusively tetraploid, from tetraploid fodder beet pollen sources
300 m
between two fodder beet seed production fields in which male sterility is not used
300 m
