The picture above is the very tap root of Bishop's Homegrown/Face Of The Earth Seed. My grandparents shortly after moving to Pekin Indiana from Greensburg KY in 1947 where they purchased the farm that is now Bishop's Homegrown. This picture was taken in Pekin in front of the old co-op next to the old railroad depot, neither of which exist today.

Terms that I use in my writings which may be useful

I was over wondering around the Native Seeds/SEARCH web-site earlier and came accross a list of terms and definitions that I thought might be useful to know while reading my blogs, articles, and research papers, I thought it would be nice to post those here for folks that aren't aquainted with the lingo of farmers and plant breeders.

Accession: Plant sample, strain or population held in a genebank or breeding program for conservation or use.

Biodiversity: The total variability within and among species of all living organisms and their habitats.

Ex Situ Conservation Conservation of a plant outside of its original or natural habitat.

Genebank: Facility where germplasm is stored in the form of seeds, pollen, etc., or in the case of a field genebank, as plants growing in the field.
Gene Pool: All the genes and their different alleles present in an interbreeding population.

Genetic Diversity: The genetic variation present in a population or species.
Genetic Erosion: Loss of genetic diversity between and within populations of the same species over time or reduction of the genetic base of a species due to human intervention, environmental changes, etc.

Genetic Resources: Genetic material of plants, animals, and other organisms which is of value as a resource for present and future generations.
Genotype: 1) The genetic constitution of an organism. 2) A group of organisms with similar genetic constitutions.
Germplasm: A set of genotypes that may be conserved or used, e.g. seeds, clones, pollen.

In situ Conservation: Conservation of plants or animals in areas where they developed their distinctive properties, i.e. in the wild or in farmers' fields.
Indigenous/ local knowledge: Knowledge that develops in a particular area and accumulates over time through being handed down from generation to generation.
Landraces: Farmer-developed varieties of crop plants that are adopted to local environmental conditions.

Plant genetic resources: The genetic material of plants, which determines their characteristics and hence their ability to adapt and survive.
Regeneration: The growing out of a sample from an accession to replenish the original accession's viability.

Wild relative: A non-cultivated species which is more or less closely related to a crop species (usually in the same genus). It is not normally used for agriculture but can occur in agro-ecosystems (e.g. as a weed or a component of pasture or grazing lands).
