|
A class |
Refers to seed and vegetative
material derived from
orchards or stool beds.
Generally seed and vegetative
lots registered as Class
A have a genetic worth
greater than zero. |
|
B class |
Refers to seed and vegetative
material derived from
natural stands. Seed
and vegetative lots
registered as Class
B are not assigned a
Genetic Worth. |
|
B+ class |
Refers to seed and vegetative
material derived from
natural stands that
have been identified
as superior provenances.
Generally seed and vegetative
lots registered as Class
B+ have a genetic worth
greater than zero. |
|
Base population |
The population of trees
from which individuals
are chosen to establish
the breeding population
and/or orchard population
for a breeding program.
Generally refers to
a wild population within
a breeding region. |
|
Breeding population
|
A set of trees within
which crosses are made
to generate material
for the next cycle of
selection. Breeding
populations are generally
large, as compared to
the production population.
|
|
Deployment |
Establishment of a new
crop through artificial
regeneration; through
physical movement from
one site (e.g. a nursery)
to the deployment site;
or through planting
or seeding designed
to meet resource management
objectives or obligations.
Afforestation, reclamation
and reforestation may
be considered to be
deployment. Natural
regeneration, even where
enhanced through silvicultural
techniques such as scarification,
is not considered to
be deployment. |
|
Genetic worth (GW) |
A measure of the genetic
quality of a seed or
vegetative lot over
wild stand material,
measured for a specific
trait (i.e., growth,
wood density, pest resistance).
|
|
Genetically modified
organism (GMO) |
An organism resulting
from the introduction,
removal, or suppression
of genes using DNA manipulation
technology. |
|
Material transfer agreement
(MTA) |
Material transfer agreements
are contractual legal
agreements between two
or more parties governing
the transfer and subsequent
use of genetic materials.
MTAs specify which rights
are conferred, and may
contain clauses concerning
such topics as record
keeping, reclaim rights,
liability disclaimers
and prohibitions on
use of the material
for further breeding.
|
|
Orchard |
For the purpose of this
document the term "orchard"
includes facilities
designed to produce
seed or vegetative propagules
for deployment purposes,
including, but not limited
to, seed orchards and
stool beds. |
|
Ramet |
An individual that has
been vegetatively reproduced
from the original plant,
or ortet, and is thus
genetically identical
to it. |
|
Reforestation |
The reestablishment
of trees on denuded
forest land by natural
or artificial means
such as planting and
seeding. |
|
Registration |
Process that allows
a seed or vegetative
lot to be used for deployment
within its SPZ. A registered
seed or vegetative lot
is one that has completed
the registration process.
|
|
Seed |
For the purpose of this
document, the term "seed"
is used to include both
seed and vegetative
propagules created for
the purpose of deployment
|
|
Seed orchard |
A stand of trees, usually
several hundred to several
thousand in number,
established and managed
primarily for early
and abundant production
of seed for deployment.
Trees in the orchard
are derived and propagated
from selected parent
trees by grafting or
by seed. |
|
Seed Planning Unit (SPU)
|
A unique combination
of species, SPZ, and
elevational limits,
used for breeding and
planning purposes. |
|
Seed Planning Zone (SPZ)
|
A map area used to guide
seed transfer. |
|
Seed production area
(SPA) |
A stand of wild or planted
trees that is delineated
and managed for the
purpose of seed production.
|
|
Select seed |
Seed of defined genetic
worth (GW), with GW
greater than zero; seed
of A class or B+ class.
|
|
Stoolbed |
An aggregation of closely
spaced stumps, or stools,
managed for the production
of vegetative sprouts
(whips). Harvested whips
are used for operational
planting stock and can
be pre-rooted prior
to deployment. |
|
Wild |
Genetic materials of
native species originating
from natural regeneration.
