Sagebrush Species Pre-Variety Germplasm Standards in California

(Artemisia spp.)

GENERAL STANDARDS -- The standards on this sheet are in part condensed and apply to sagebrush species. For greater detail and additional provisions, see the Pre-Variety Germplasm Standards.

APPLICATION -- Applications should be submitted electronically on CCIA’s website (http://ccia.ucdavis.edu) no later than three (3) weeks after planting.  Applications for G0 collections must be submitted two (2) weeks prior to seed colleciton. New applicants should contact the CCIA office for instructions.

FIELD HISTORY -- Field history requirements do not apply to G0 collections.  For G1-G10 production, land must have no prior Artemisia species production for at least 2 years.  Sagebrush must be planted in distinct rows. Exceptions must be approved by the Seed Certification Office prior to planting.

ISOLATION -- Seed fields must be isolated from other pre-variety germplasm selections, varieties, or wild populations of Artemisia spp. by the following distances*:

Factor

G0

G1

G2

G3

G4-G10

Less than 5 acres

N/A

900 feet

450 feet

330 feet

165 feet

More than 5 acres

N/A

600 feet

303 feet

165 feet

165 feet

*A seed field located within the same geographic source area as was identified for the germplasm entity being increased does not require isolation from naturally occurring plants of the same species adjacent to the seed field. 

FIELD INSPECTION -- Include a seedling and a seed crop inspection. G0 collection site inspections may take place prior to, during, or after collection.

Off-Types -- Every field should be rogued to remove any plants of another crop or variety, including volunteers. Pre-variety germplasm selections cannot always be differentiated at field inspection. When differences can be distinguished, the maximum mixture of other varieties or definite off-types permitted is as follows:

Factor

G0

G1

G2

G3-G10

  Other varieties &
  off-types

N/A*

1:1,000

1:500

1:250

  Other kinds (inseparable
  other species)

N/A*

1:2,000

1:1,000

1:500

*Individuals collecting G0 seed must be knowledgeable in their ability to distinguish Artemisia species.

Weeds -- Fields (G1-G10) must be free of any noxious weeds with a prohibited seed rating. Noxious weeds with a restricted seed rating and common weeds difficult to separate must be controlled. Noxious weeds with Prohibited and Restricted seed ratings are listed in the California Seed Law/CA Code of Regulations/Sections 3854 and 3855. See California Seed Law - Prohibited and Restricted Noxious Weed List.  Individuals collecting G0 seed must be knowledgeable in their ability to identify noxious weeds with prohibited and restricted seed ratings that are common present in the collection area.

Fields may be refused certification due to unsatisfactory appearance caused by weeds, poor growth, poor stand, disease, insect damage, and any other condition that prevents accurate inspection or creates doubt as to identity of the germplasm entity.
