Landrace

Under landraces or natural races is usually understood breeds of animals or plants ( there often referred to as a landrace ) located in an area with no systematic cultivation (see animal breeding ) have formed. These landraces are often characterized by special adaptations to the environmental conditions of the development area.

Landraces are often the starting point for further breeding, sometimes the original names are preserved. An example of this is the German Landrace, a widespread domestic pig breed that is subject to a systematic breeding, but still bears this name.

In general, the degree of processing of a breeding Landrace in the literature is described differently. Thus we find, for example, the following definition for botany:

" Landraces are local plant populations that have been bred over hundreds or even thousands of years by farmers. These populations can be distributed across an entire geographic region or occur only in a certain valley or mountains. Each landrace possesses due to the selection certain alleles that are beneficial for good prosperity and successful reproduction in the respective area of ​​distribution. "

While it ( already ) is called in the manual of the entire domestic animal breeding for agriculturists of 1848:

"The creation and training, or the preservation of strains ( or if you prefer: Breeds ) but and strokes is not dependent on a loser or prolong stays these animals in a peculiar area, locality and climate, but is dependent on the exact following the correct principles of breeding [ ... ]. The animals of an area may only be referred to as " land race " if they have been trained for independent tribal (race, family), [ ... ]. "

Is in common in the literature assumed that landraces occur under the influence of the environment on its own.
