The leaders in tree breeding in BC are: |
- Forest Genetics Council of BC - SelectSeed Ltd - Tree Improvement Branch - Research innovation and Knowledge Management Branch - ArborGen - Seed Orchard Managers |
|
|
Section 8 of Chief Forester's Standards for Seed Use describes 6 classes of genetic material. The classes are: |
- Natural stand - Untested parent trees - Superior provenance - Tested parent trees - Custom lot - Non-BC sources |
|
|
SPZ means |
Natural stand Seed Planting Zone |
|
|
BGC means |
Biogeoclimatic zone |
|
|
QCI Means |
Queen Charlotte Islands |
|
|
What is SPAR |
Seed Planning and Registry System. Specifies seed transfer limits for each seed lot in the communication system |
|
|
(T or F) Only genetic material used according to Transfer Limits specified by Regulation may be used to reforest Crown Land in BC |
True |
|
|
(T or F) All genetic material used to reforest Crown Land in BC must be registered by the Ministry of Forests and stored at the Tree Seed Center |
True |
|
|
(T or F) GMO's should be registered |
False - No GMO's may be registered |
|
|
(T or F) Collections from plantations may be registered |
False - No collections from plantations may be registered |
|
|
(T or F) All mixes must be registered |
False - No mixes may be registered |
|
|
(T or F) Each unique collection of genetic material is assigned a Seedlot Number or Vegetative Lot number and transfer limits |
True :) |
|
|
(T or F) The minimum parental contribution is 10 trees for natural stands |
True :P |
|
|
(T or F) Genetic material must be used according to Regulations |
True |
|
|
(T or F) Records must be kept of where material is used and reported to the government annually |
True |
|
|
(T or F) The best available genetic quality material must be used last |
False - the best available genetic quality material must be used first |
|
|
The best available genetic material is the seedlot listed on SPAR with the following attributes: |
- Highest Genetic Class and Genetic Worth - Of a preferred species to be planted - Meets transfer rules for use in a specified location Available surplus (SPAR code for "on sale") |
|
|
Define Genetic Worth |
It is the ranking system for breeding attributes; Growth, wood relative Density and pest Resistance expressed as a % increase compared to natural stand averages |
|
|
(T or F) 95% of genetic material used by a Licensee in any year must comply with regulations |
True |
|
|
a Seed Planning Zone (SPZ) |
Describes areas in which genetic material may be used. Similar to BGC zones. |
|
|
There are two sets of SPZ's: |
Those for genetic material from natural stands and those from tested parent trees |
|
|
Transfer limitations |
- Elevation - Latitude - BCG |
|
|
What is an SPU |
A Seed Planning Unit. SPU's are related to SPZ's but SPU's may vary in extent because of the confidence gained through testing |
