Wildorigin

Wildorigin is a term used in biology and conservation to denote the natural origin of a species, lineage, or genetic material in wild populations, rather than from domesticated, cultivated, or laboratory sources. In this usage, wildorigin emphasizes the provenance and genetic integrity of material that exists in the wild as opposed to being derived from human selection or cultivation.

In plant breeding and conservation, wild-origin germplasm or wild-origin populations are collected from natural habitats and stored in gene banks to preserve genetic diversity. Such material can provide traits valuable for crop improvement, including disease resistance, drought tolerance, and tolerance to abiotic stresses. When researchers refer to a crop as having wild-origin ancestry, they typically mean that some portion of its genome traces back to wild relatives.

Challenges include accurately determining origin due to feral populations, mislabeling, and genetic admixture. Collecting wild-origin material often requires permits and adherence to biodiversity and access-and-benefit sharing regulations. In conservation, maintaining wild-origin populations is important for preserving ecological interactions and evolutionary processes.
