The general planting stock certification standards are further defined to apply specifically to hemp planting stocks. Classes and sources of certified planting stocks are:

(1) Breeder plant stock (source seed) is propagation material identified by the breeder, or the breeder's representative. The breeder must also declare and document the way parent lines are selected and how the plant stock is maintained.

(2) Mother plant is a plant produced from a breeder plant stock.

(3) Certified plants are plants produced from mother plants. Certified plants may be used to produce certified stock in the growth facility or D1 daughter stock. Certified plants are propagated as follows:

(a) Mother plants may be cut repeatedly to produce D1 daughter plants. D1 daughter plants are produced by cuttings from mother plants.

(b) D1 daughter plants may be cut repeatedly to produce D2 daughter plants. D2 daughter plants are produced by cuttings from D1 daughter plants.

(c) D2 daughter plants may be cut repeatedly to produce D3 daughter plants. D3 daughter plants are produced by cuttings from D2 daughter plants.

(4) The grower shall retain documentation of the parent being used to generate clones.

(5) All grower records and grower developed best management practices (BMPs) related to the production of hemp clones shall be available for inspection by the certifying agency.
