Current through Register Vol. 48, No. 9, September 27, 2024
I. Application of
Genetic Certification Standards
A. The
General Certification Standards, Clemson University Regulation
27-190,
as adopted are basic and applicable and together with the following specific
standards constitute the standards for certification of hemp, as well as any
standards approved by the Association of Official Seed Certifying Agencies
(AOSCA) Standards Council.
B. The
Genetic Standards by AOSCA are modified as follows:
1. All production of hemp crops are subject
to license application approval that may be required by regulatory
authorities.
2. Only varieties of
hemp approved by regulatory authorities are eligible for
certification.
3. The allowable
area of a hemp research area or production field may be determined by state or
local agencies.
4. Growers may be
required by regulatory agencies to obtain THC test results according to
applicable regulations. Growers may be required to submit these results to the
seed certifying agency before a crop certificate is issued.
II. Land Requirements
A. Hemp crops for Foundation and Registered
classes must not be grown on land which in any of the preceding 3 years
produced a crop of hemp.
B. Hemp
crops for Certified classes must not be grown on land which:
1. In the preceding year produced a certified
crop of the same variety.
2. In
either of the preceding 2 years produced a non-certified crop of hemp or a
different variety of hemp.
C. Weeds
1.
The presence of Broomrape (Orobanche spp.) in hemp crops is cause for declining
certified status.
III. Field Standards
A. Crop Inspection
1. It is the grower's responsibility to
ensure that fields are inspected by an authorized inspector at least once prior
to swathing or harvesting, except in the case of Foundation, Registered, and
Certified monoecious types and unisexual hybrids and Foundation dioecious
types, in which 2 inspections are required.
2. A field that is cut, swathed or harvested
prior to crop inspection is not eligible for certification.
3. Fields must be inspected at a stage of
growth when varietal purity is best determined. Crops not inspected at the
proper stage for best determining varietal purity may be cause for declining
certified status.
4. First
inspection for all classes of monoecious types must be made just before or at
early flowering. First inspection for all classes of dioecious types must be
made after flowering when male plants are beginning to senesce.
5. Second inspection for all classes of
monoecious types, and the Foundation class of dioecious types must be made when
seeds are well forming.
6.
Isolation areas will be inspected for volunteer hemp plants on each
inspection.
B. Isolation
1. The area, density, stage of maturity and
location of any contaminating pollen source is an important factor in cross
pollination, and therefore must be noted on the Seed Crop Inspection Report for
consideration in determining certification status. There shall not be any
Cannabis sativa L. plants within 100 m of the crop and not more than 10
plants/ha beyond 100 m within the isolation requirement.
2. The required isolation must be present
prior to flowering and crop inspection.

C. Impurity Standards
Impurities should be removed prior to crop inspection.
Any combination of impurities may be reason for declining
certified status.
Table 2 indicates the maximum number of impurities permitted by
AOSCA in approximately 10,000 plants of the inspected crop. The inspector makes
at least 6 counts (10,000 plants each) or the equivalent to determine the
number of impurities. The resulting average of these counts must not exceed the
maximum impurity standards in Table 2.

B. Guidelines for the Production of Certified
Hemp Seed
1. Definitions
a. "Hemp" (Cannabis sativa L. supsp.sativa.)
includes varieties of these kinds:
i.
Dioecious type: with male and female flowers on separate plants.
ii. Monoecious type: with male and female
flowers on the same plant.
iii.
(Unisexual Female) Hybrids: with sterile male and fertile female flowers on the
same plant.
b. "Approved
Cultivar" means any variety designated as eligible for production by federal or
local regulatory authorities
c.
"THC" means delta-nine ([DELTA] 9) tetrahydrocannabinol, which is the component
of Hemp regulated by federal or local regulatory authorities.
Although traditionally a crop with a Dioecious plant type, many
Monoecious varieties of hemp (Cannabis sativa L. supsp.sativa) have been
developed. Hemp is sexually polymorphic and often produces many different
ratios of intersexual plant types that can increase roguing requirements.
Variety descriptions normally define these ratios.
d. "Foundation Seed Production" includes any
means of processing or conditioning of seed from a Foundation production area
which may contaminate the varietal purity of the seed is prohibited.
C. Area of Foundation
Fields
When unforeseen circumstances do not permit proper maintenance
of the entire field, it is recommended that the area be reduced by destroying
part of the field or by isolating a part to meet the requirements of a lower
status of certified seed. The remainder of the field must meet the requirements
for Foundation field production.
The area of a Foundation field includes the "walkways" provided
within the field to facilitate effective roguing.
D. Recommended Production Procedures
Field Planting
1.
Fields should be planted to facilitate inspection, roguing and
harvesting.
2. Fields should be
planted in areas easily accessible for frequent maintenance and to provide the
maximum protection from outside sources of contamination, such as roadways and
building sites.
3. Regulations for
land requirements are minimum standards and caution is necessary in choosing
land, as volunteer growth from previous crops may vary according to local
conditions.
4. The regulations for
isolation are minimum standards. It is always to the grower's advantage to
provide more isolation than required. When planting Foundation fields, specific
requirements may influence the location and size of the field. It is a
safeguard if adjacent crops are the same variety as the field and are inspected
for certified status.
E.
Roguing
1. The field must be thoroughly and
intensively rogued many times throughout the crop season.
Off-type male flowers must be removed before the receptive
stage of female flowers in the inspected crop.
2. The numbers and kinds of plants removed
should be recorded and described on the appropriate forms.
3. All male flowers rogued from the crop must
be removed from the production area and burial is recommended.
4. Regrowth of rogued flowers or plants must
be prevented.
F.
Harvesting, Cleaning and Storing
1. A seed
grower should have access to the necessary equipment for harvesting and
cleaning the seed from the field in such a manner as to ensure that the
varietal purity of the seed is maintained.
2. The seed should be stored, in compliance
with federal or local regulations, in a clean, cool, dry area.
3. The seed containers should be labelled for
identification.
It is recommended that not more than one variety of Hemp be
grown under the management of one grower.
V. Vegetatively Propagated Hemp

follows:
1. Mother Plants may be cut
repeatedly to produce D1 Daughter Plants. D1 Daughter Plants are produced by
cuttings from Mother Plants.
2. D1
Daughter plants may be cut repeatedly to produce D2 Daughter Plants. D2
Daughter plants are produced by cuttings from D1 Daughter Plants.
3. D2 Daughter plants may be cut repeatedly
to produce D3 Daughter plants. D3 Daughter plants are produced by cuttings from
D2 Daughter plants.

A.
Application and Amplification of General Certification Standards
1. The General Certification Standards,
Clemson University Regulation
27-190,
as adopted are basic and applicable and together with the following specific
standards constitute the standards for certification of hemp transplants; a.k.a
seedlings, plugs.
2. Section V. of
the General Standards is amplified as follows to apply specifically to hemp
seedling certification.
3. All
Certified transplants must be grown from a class of certified seed or certified
clones. Proof of seed/clone eligibility shall be established by providing
either a certified tag/label with invoice showing the lot number and pounds
received or documentation of clone propagation under clone standards found in
the Seed Certification Handbook.
4.
Seed coated or pelleted by non-approved conditioners will not be eligible for
certification
5. All containers
must be labeled in a manner that maintains the source, identity and
certification eligibility of the transplants. All containers offered for sale
must be identified by the official seed certification tag/label. The tag/label
must be affixed (stapled, for example) to trays so tags/labels are not
misplaced.
B.
Definitions
1. Transplants: hemp plants that
originate from either seed or clones that are kept in a vegetative state
(before flowering) that will be moved to another production site.
2. Clones: are asexually propagated progeny
genetically identical to the stock plant.
3. Seedlings: plants grown from
seeds.
4. Plugs: young plants
raised in small, individual cells, intended for transplanting at another
production site.
C.
Growth Facility, Field and Transplant Standards
1. Traditional outdoor plant beds (fields)
will be inspected at least two times for phenotypic purity, isolation, general
physical condition, and appearance of plants.
2. Growth facility produced plants shall be
inspected at least two times for varietal labeling, phenotypic purity,
isolation, general physical condition, and appearance of plants.
3. Maximum off-type or other variety shall
not exceed 0.2%, or 20 in 10,000. Non-conforming plants must be removed and
destroyed.
4. At the time of the
final inspection, the number of transplants produced must be verified by agency
personnel.
5. Transplants may be
rejected for non-compliance with these standards.
6. Inspectors may also reject transplants due
to unsatisfactory appearance such as any plants that are diseased, insect
infestation, or otherwise stressed or any condition which prevents thorough
inspection.
Unlabeled or inadequately labeled transplants will be
ineligible for certification.
7. At the final inspection, transplants may
be collected for post-control grow outs or other identification verification
tests if required by agency.
8.
Certifying agency personnel may conduct additional inspections as necessary to
ensure certification standards are met.
D. Growth Facility, Plant Bed Soil Mix
Requirements
1. Hemp transplants must not be
grown on traditional outdoor plant beds (fields) which:
a. In either of the preceding two years
produced a non-certified crop of hemp or a different variety of hemp.
b. In the preceding year produced a certified
crop of a different variety
2. Hemp transplant growers using growth
facilities must use a SOP (Standard Operating Procedure) and document that the
facility is free of any plant material from a previous crop.
3. For growth facility production of
transplants, the soil mix must be new, soil-less media, or sanitized soil
mixes.
4. The presence of Broomrape
(Orobanche spp.) in hemp crops is cause for declining Certified
status.
E. Growth
Facility Isolation Standards
When two or more varieties are being grown in the same
greenhouse or traditional outdoor plant bed (field), there must be an 18"
unplanted area between the varieties. The production area, flats and/or
containers for each variety must be clearly labeled in a manner that prevents
mixing or misidentification.

harvesting, and transplant sales in a manner that prevents the accidental or
mechanical mixture of containers of different varieties.
F. Labeling Standards
All certified transplants offered for sale must be labeled with
official certification tags or labels. Each container of transplants must have
an agency certification label firmly attached to be sold as certified
transplants. Failure to properly label transplants at the time of sale, will
revoke the certification status and will result in not being eligible for sale
as certified transplants.

G. Guidelines to Produce Certified Hemp Seed
1. Certified Seed Production
Although traditionally a crop with a Dioecious plant type, many
Monoecious varieties of hemp (Cannabis sativa L. subsp. sativa) have been
developed. Hemp is sexually polymorphic and often produces many different
ratios of intersexual plant types that can increase roguing requirements.
Variety descriptions normally define these ratios.
a. Quality Assurance (QA) Program standards
will be equal to or exceed the AOSCA Standards for certification for varietal
purity of the Certified class of seed, with the following exceptions:
i. Varietal eligibility
requirements
ii. Seedstock
eligibility
b. Any means
of processing or conditioning of seed from a production area which may
contaminate the varietal purity of the seed is prohibited.
2. Area of Fields
a. When unforeseen circumstances do not
permit proper maintenance of the entire field, it is recommended that the area
be reduced by destroying part of the field or by isolating a part to meet the
requirements. The remainder of the field must meet the requirements for
certified field production.
b. The
area of a field includes the "walkways" provided within the field to facilitate
effective roguing and inspecting.
3. Recommended Production Procedures
Field Planting
a.
Fields should be planted to facilitate inspection, roguing and
harvesting.
b. Fields should be
planted in areas easily accessible for frequent maintenance and to provide the
maximum protection from outside sources of contamination, such as roadways and
building sites.
c. Regulations for
land requirements are minimum standards and caution is necessary in choosing
land, as volunteer growth from previous crops may vary according to local
conditions.
d. The regulations for
isolation are minimum standards. It is always to the grower's advantage to
provide more isolation than required. When planting fields, specific
requirements may influence the location and size of the field. It is a
safeguard if adjacent crops are the same variety as the field and are inspected
for certified status.
4.
Roguing
a. The field must be thoroughly and
intensively rogued many times throughout the crop season.
b. Off-type male flowers must be removed
before the receptive stage of female flowers in the inspected crop.
c. The numbers and kinds of plants removed
should be recorded and described on the appropriate forms.
d. All male flowers rogued from the crop must
be removed from the production area and burial is recommended. The male flowers
should be bagged during removal to prevent unwanted pollen transfer during
removal.
e. Regrowth of rogued
flowers or plants must be prevented.
