Chapter I

GENERAL PROVISIONS

Article 1. Scope

This Circular provides for the list of major forest tree species; recognition of cultivars and cultivar sources; management of major forest tree cultivar materials.

Article 2. Regulated entities

This Circular applies to domestic and foreign organizations and individuals engaging in recognition of cultivars and cultivar sources, and management of major forest tree cultivar materials.

Article 3. Definitions

1. “major forest tree species” mean species of timber trees and non-timber forest trees that meet the criteria specified in Article 4 of this Circular.

2. “major forest tree cultivars” mean cultivars of major forest tree species.

3. “cultivar source” means a place that provides propagating materials, including selected forest stands, transformed cultivar stands, planted cultivar stands, cultivar gardens, plus trees and hedge orchards.

4. “selected forest stand” means a natural forest or planted forest that has above average quality and is selected to temporarily provide cultivars for production but has not yet been affected by silvicultural techniques or assessed to be recognized as a transformed cultivar stand.

5. “transformed cultivar stand” means a cultivar stand selected from the best forest stand in a natural forest or planted forest and affected by silvicultural techniques as prescribed to have cultivars.

6. “planted cultivar stand” means a stand that is planted with seedlings grown from seeds collected from plus trees and is not planted according to a planting plan.

7. “cultivar garden” means a garden that is planted according to a certain planting plan, from clones (clonal cultivar garden) or seeds of plus trees (sexual cultivar garden) that have been selected and recognized.

8. “plus tree” mean the best trees which are selected from natural forests, planted forests, scattered trees, cultivar stands or cultivar gardens and from which propagating materials are taken.

9. “original ortet” means a tree that produces high yield, has high quality and is resistant to pests and adverse conditions in a manner that is better than other trees in a population recognized through a clonal test to provide vegetative propagating materials.

10. “hedge orchard” means an orchard that is planted with clonal cultivars propagated from original ortets to provide materials for producing clonal cultivars.

11. “cultivar material” means a cultivar used for planting forests or propagating materials.

12. “propagating material” means a seed, whole plant or parts thereof used to produce a cultivar.

13. “cultivar test” means a monitoring and evaluation process that is gone through under certain conditions and during a certain time period in order to determine the cultivar’s yield, quality and resistance to pests and adverse conditions.

14. “planting trial” means the planting trial that is carried out on an area and during a certain time period to assess and compare yield and quality of trial cultivar with those of control cultivar.

15. “fast-growing species” mean those that reach an average annual diameter growth of at least 02 cm/year or average yield of at least 10 m³/ha/year in a business cycle.

16. “slow-growing species” mean those that reach an average annual diameter growth of less than 02 cm/year or average yield of less than 10 m3/ha/year in a business cycle.
