Abstract
La producción natural de perdiz roja en España no satisface la demanda cinegética, por ello se realizan rutinariamente repoblaciones con perdices criadas en granjas. En ocasiones, se han introducido fraudulentamente especímenes foráneos, sobre todo de perdiz turca, que puede hibridar con la roja, produciéndose un fenómeno de introgresión genética. En este trabajo se analizan secuencias de DNA mitocondrial de perdices híbridas recogidas en granjas y en cotos de localidades repartidas por la geografía española y se comparan con secuencias de perdiz turca de múltiples orígenes. Los resultados corroboran la procedencia oriental detectada previamente e indican que todas las secuencias de perdiz turca dispersas en la geografía española tienen un origen muy restringido.
The natural production of red-legged partridge in Spain does not meet hunting demand, so stocking with fowl-run reared partridges is routinely performed. Sometimes, specimens of foreign origin, especially the chukar partridge have been fraudulently introduced. Chukar partridge can hybridize with the red-legged partridge, resulting in genetic introgression. In this paper, mitochondrial DNA sequences of partridges collected in fowl-runs and hunting areas throughout the Spanish geography are compared with sequences of chukar partridge from multiple sources. The results of this study corroborate the oriental origin previously reported and suggest that all the chukar partridge sequences scattered in the Spanish geography have a very restricted origin.
