(a) Designated stands or trees means stands or trees which have been inspected and approved for the collection of seed or vegetative propagation material in accordance with the standards and procedures outlined in the “standards”.

(b) Field shall be interpreted to include “stand”, “orchard” and “trees” from which tree seed may be collected.

All forest tree improvement terms are defined in accordance with “Glossary for Forest Tree Improvement Workers” E.B. Snyder, Editor, published 1959 by Southern Forest Experiment Station. U.S.F.S.

A group of plants derived from a single individual (ortet) by a sexual reproduction. All members (ramets) of a clone have the same genotype and consequently tend to be uniform.

The quality of the tree so designated has been verified by appropriate testing, as superior or desirable under a specified propagation system. The superiority of crossbred parents is evaluated by means of the progeny test. That of inbreds is evaluated by observing the inbred lines; that of clones by clonal tests.

The one plant from which members of a clone were originally derived.

The demonstrable characteristic(s) of an organism; the product of the interaction of the genes of an organism with the environment.

Evaluation of individuals by the performance of their offspring.

A plant part such as a bud, tuber, root, or shoot, used to reproduce an individual asexually.

A plantation consisting of clones or seedlings from selected trees, isolated to prevent pollination from outside sources, and cultured for early and abundant production of seed for reforestation. Forest seed orchards are often established while genetic evaluation of the material is under way. When results of these tests are known, the undesirable individuals are rogued.

Propagation of a plant by asexual parts, as in budding, dividing, grafting, rooting, and air layering. Hereditary factors or genes of the resulting clone (ramets) are identical with those of the original plant (ortet).
