A landrace is a locally adapted, genetically diverse traditional variety of a domesticated plant or animal that developed through generations of farmer selection and adaptation to a specific environment and culture, rather than through a formal breeding program. Landraces carry genetic diversity that formal breeding often narrows away, and many modern crop and livestock breeding programs now draw on landrace populations as a genetic reservoir even as landrace cultivation itself has declined with the spread of uniform modern varieties.

Terminology
The term was first defined by Kurt von Rümker in 1908, and more clearly described in 1909 by U. J. Mansholt, who wrote that landraces have more stable characteristics and better resistance to adverse conditions, but have lower production capacity than cultivars, and are apt to change genetically when moved to another environment.
