Chapter 5. General Seed Certification Requirements

§501. Definitions also Applicable to this Chapter
(Formerly §125)


Certification―the process by which official recognition is given to seeds produced under a limited generation system which ensures genetic purity and identity and a given minimum level of quality.

Clonally Propagated Plant—a plant that is duplicated or propagated as a plant clone from vegetative cuttings or plant divisions using one or more of an aerial stem, rhizome, stolon, leave, or root.

Germination―the percentage of seeds capable of producing normal seedlings under ordinarily favorable growing conditions.

Hybrid―one or more crosses of inbred lines of the same kind of seed.

Inbred Line―a relatively true-breeding strain resulting from at least five successive generations of controlled self-fertilization or of backcrossing to a recurrent parent with selection, or its equivalent for specific characteristics.

Inert Matter―all matter not seeds, including pieces of broken and damaged seeds one-half or less than the original size, sterile florets, fungus bodies, stones and all matter considered as inert by the Association of Official Seed Analysts Rules for Testing Seeds.

Inseparable Seeds―seeds that are similar in size, shape and weight to the seed offered for certification, which are difficult to remove.

Isolation―the distance required between a crop or variety entered for certification and other plantings of the same crop or variety, not entered for certification, which are pollinating at the same time.

Kind―one or more related species singly or collectively known by one common name (examples: corn, beans, wheat).

Land Requirement―the period of time during which a field entered for certification cannot have grown or been seeded to the same species or variety except a certified class of the same species or variety which was equal to or superior to that of the species or variety entered for certification. If a field(s) is(are) entered for certification in the foundation class, only the foundation class of seeds could have been grown in that field during the time period specified.

Lot of Seed―a definite quantity of seeds identified by a lot number or mark, every portion or bag of which is uniform, within permitted tolerances, relative to the factors which appear in the labeling.

Noxious or Prohibited Weeds―all weeds designated as noxious or prohibited weeds under §109.

Off-Type (Mutations)―plants or seeds which deviate in one or more characteristics from the breeder description filed with LDAF.

Open-Pollination―pollination that occurs naturally as opposed to controlled pollination such as by detasseling cytoplasmic male sterility, self-incompatibility or similar processes.

Originator―a person, company, agent or institution developing a new variety of seed.

Other Weeds/Weed Seeds―all weeds and/or weed seeds which have not been designated as noxious weeds by the Commission.

Plant Clone—a genetically identical plant or plant material derived originally from a single ancestor individual over one or more vegetative generations.

Recertification―the official approval of a second or subsequent generation of a certified class of seed.

Roguing―the removal from the field of noxious weeds, off-type plants, varietal mixtures and any other plants producing seeds which are inseparable from seeds of the crop to be certified.

Species―plants designated by a common name and having common characteristics.

Unit of Certification―any clearly defined field(s) or portion(s) of a field entered for certification.

Variety―a subdivision of a kind, characterized by growth, plant, fruit, seed or other characteristics by which it can be differentiated from other seeds of the same kind.

Volunteer Plants―plants of a crop kind or species other than the crop being certified that are present in a field.

Weight Unit―unit of measure, designated by the Commission, based on the most common industry accepted packaging weight in pounds for a specific commodity.

§503. Classes of Seed (Formerly §123)

A. The following classes of seed are recognized for purposes of this Chapter.

1. Breeder Seed (White Tag)―seed directly controlled by the originating or sponsoring plant breeding institution, firm or individual which is the source for the production of seed of the certified classes.

2. Foundation Seed (White Tag)―progeny of breeder or foundation seed, handled so as to maintain specific genetic purity and identity, production of which must be acceptable to LDAF.

3. Registered Seed (Purple Tag)―progeny of breeder or foundation seed, handled under procedures acceptable to LDAF to maintain satisfactory genetic purity and identity.

4. Certified Seed (Blue Tag)―progeny of breeder, foundation or registered seed, handled under procedures acceptable to LDAF to maintain satisfactory genetic purity and identity.

5. Tree Seed

a. Certified Tree Seed (Blue Tag)―seed from trees of proven genetic superiority, produced so as to assure genetic identity. Seeds from interspecific hybrids of forest trees may be included.

b. Selected Tree Seed (Green Tag)―progeny of rigidly selected trees or stands of untested parentage that have promise but not proof of genetic superiority and for which geographic source and elevation is stated on the label.

c. Source-Identified Tree Seed (Yellow Tag)―seed from a natural stands with known geographic source and elevation, or plantations of known geographic origin and which is acceptable to LDAF.
