Genetic Conservation

First Era: tree introduction, species trail,

botanical garden)

Second Era: tree breeding

(provenance trails, progeny test)

Third Era: Linked with breeding

& biotechnology – DNA Molecular)

Lesson learned from experience

  • Seed source from (improved) plantation

is better than from natural forest.

  • Breeding strategies of (each) species

should be developed.

  • Biotechnology help to enhance

effectiveness and speed up of improved seed source establishment.

  • Seed exchange is necessary for effective

genetic test.

slide-24
SLIDE 24

Approaches under Climate Changes: Options for future management

  • Develop specific breeding program

(well adapted to changing environment)

  • Ensuring quantity and quality of

seed sources

  • Establish static conservation

(Cryopreservation, cold storage freeze preservation of vegetative part) to preserve improved genetic materials
