ONION SEED
CERTIFICATION
REQUIREMENTS AND STANDARDS
I. BASIC
RULES
The UCIA General Seed
Certification Requirements and Standards are basic and with the following
constitute the requirements and standards for onion seed certification.
II. SEED
PRODUCTION
A. APPLICATIONS
Date and fees for applications are
as listed in the General Requirements and Standards.
B. SEED
ELIGIBILITY
1. Onion
varieties currently certified in Utah are listed in Prefix A.
2. Foundation
or Registered bulbs must be planted to produce Certified class seed, or
Foundation class seed may be planted to produce Certified class seed without a
intervening bulb selection process.
Shipment of onion bulbs into the state or within the state to be used as
Mother bulbs (of the proper class) for seed production must be sacked and
sealed by the proper certification agency at the point of origin.
3. For
the Utah strain of Yellow Sweet Spanish onions, a bulb selection program may be
accomplished under strict supervision of the UCIA for Foundation class
production of bulb grading and selection (bulbsof bulbs and Certified class
production of seed and may be repeated as follows: (a) bulb grading and
selection (bulbs must originate from a recognized Utah strain selection program)
for varietal type improvement (shape and color); (b) Certified class seed production from these selected
bulbs; (c) seed planted and the
Foundation class mature bulbs again selected as in part (a).
C. LAND REQUIREMENTS
1. Onions
shall be grown on land on which the preceding crop was of another kind or
produced a class of certified seed of the same variety.
2. Number
of varieties per farm
a. Seed
-- Only one variety shall be grown for seed on a farm in any one year unless
special permission is granted by the UCIA.
b. Bulbs
-- Two varieties of onions which can easily be identified by color of bulb may
be grown on the same farm in any one year.
3. Isolation -- To be eligible for certification
a
seed field must be isolated from fields of any other variety or fields of the
same variety that do not meet the varietal purity requirements for
certification as follows:
Class Feet
Foundation 5,280 (1 mile)
Registered 2,640
(1/2 mile)
Certified 1,320
(1/4 mile)
4. The
unit of certification is an entire field, and a field of seed cannot be divided
for the purpose of certification.
D. FIELD
STANDARDS
1. Two
field inspections will be made, one at the harvest and/or selection of the
bulbs (including bulbs originating in another area) and one after the seed
heads have been formed from the bulbs the next season.
2. Fields
must be rogued prior to field inspection, to remove off-type plants and other
varietal mixtures. Varietal
differences of growing onion plants are slight; therefore, varietal differences
must be determined by bulb inspection.
3. Bulb
standards -- Bulbs of any class must be uniform in size, shape, and color. Varietal mixture shall not exceed 0.5%
(0.1% for Foundation). Bulbs must
be at least 2 1/4 inches in diameter, firm and free from decay.
E. HARVEST
1. Storage
of bulbs -- Growers who have onion bulbs eligible for certification shall work
out a satisfactory plan with a UCIA representative for maintaining the identity
of the bulbs through harvest and storage.
Certified onion bulbs must be kept separate from any non-certified bulbs
at all times.
2. Containers
used for collecting seed heads must be clean and identity maintained with
proper labeling and separation from other lots.

B. A
representative sample of at least 8 ounces will be drawn from each lot by a
UCIA representative for germination and purity tests.
C. Seed
must be stored in new bags, and must have a tag and seal affixed by a UCIA
representative with notation of number of pounds on each tag. Re-packaging into smaller bags or boxes
(after coating or other processing) must satisfy the UCIA representative that
genetic purity and lot identity has been maintained. Certification tags and/or seals must be affixed to the smaller
packages if they are to be sold as certified seed.
