Section XIII-811 - Tree Seed Certification Standards (Formerly Section 215)A. Classes of Seed 1. Only the following classes of tree seed shall be recognized in tree seed certification: b. selected (green tag); andc. source-identified (yellow tag).2. For all classes of forest tree seed, the exact geographic source of the parent trees and the stand must be known. Location of the source shall be given at least down to the section or comparable land survey unit. (Alternatively, in the case of seed from seed orchards containing selected stocks from a number of separate sections, the location of the orchard shall be given and the exact source of its individual components shall be kept on file and furnished on request.)B. Land Requirements. Elevation to the nearest 500 feet of the original geographic source and the average height and age of the trees from which seed has been collected shall be shown on the tag for all forest tree seed. If available, site index (the capacity of a given site to produce trees as measured by the height of the trees at a specified age) may be recorded instead of tree height and age.C. Field Inspection. A field inspection must be made prior to flowering.D. Field Standards 1. Unit of Certification. An individual tree, clone or stand of trees may be certified in producing certified or selected seed.2. Isolation. For certified or selected seed, an adequate isolation zone shall be maintained free of off-type plants and other species which might crosspollinate producing trees. There shall be no isolation requirements for source-identified trees.3. Progeny Testing. All clones used in seed orchards shall be progeny tested.E.
