- Living genetic resources such as seeds or tissue that is maintained for the purpose of animal and plant breeding, preservation, and other research uses.
- The form of seed collections stored in seed banks, trees growing in nurseries, animal breeding lines maintained in animal breeding programs or gene banks.
Biological Diversity
- Often used to refer to the total number of different species on Earth
- Living organism from all sources including inter alia, terrestrial, marine and other aquatic ecosystems and ecological complexes.
- There are 3 aspects of biodiversity :
Genetic Diversity - genes within a species
Ecosystem (Habitat) Diversity - a higher level of organisation on earth habitat, topography, elevation, natural vs agroecosystem.
Species Diversity - species in an ecosystem
Genetic resources the self maintaining diversity of organism developed over evolutionary time. Genetic resources are measurable at species, molecular and sub molecular levels.
Type of genetic resources :
- Wild relatives
- Weedy relatives
- Primitive cultivars or land races
- Modern cultivars
- Advanced breeding lines
- Genes from other species
