CELERIAC (TURNIP-ROOTED CELERY)Apium
graveolens (L.) var.rapaceum DC.
I. Application and Amplification of General Seed Certification Standards
The General Seed Certification Standards are basic and, together with the following specific standards
constitute the standards for certification of celeriac seed.
II. Land requirements
Land to be used for seed production of celeriac seed shall be free of volunteer plants.
III. Field Inspection
A. Mother root production stage
A minimum of two inspections shall be made as follows;
1. the first inspection shall be made after 30-40days of the sowing in order to determine isolation,
volunteer plants, outcrosses, offtypes including bottlers and other relevant factors.
2. the second inspection shall be made after the mother roots have been lifted to verify
the true characteristics of roots.
B. Seed production stage
A minimum of two inspections shall be made as follows;
1. the first inspection shall be made before flowering stage to check isolation offtypes,
designated diseases and other relevant factors.
2. the second inspections shall be made at maturity and prior to harvesting.
IV. Field Standards
A. General requirements
1. Isolation
Seed fields shall be isolated from the contaminants shown in the column1of the Table below
by the distances specified in columns 2, 3,4 and 5 of the said Table:
