The analysis of morphological characters J Jordana J Piedrafita A Sanchez Universitat Autònoma de Barcelona Unitat de Genètica i Millora Animal Departament de Patologia i de Produce Animals Facultat de Veterinària 08193-Bellaterra Barcelona Spain Received 27 July 1990 accepted 19 December 1992 Summary - The relationships between 10 Spanish dog breeds have been studied using qualitative and quantitative analyses of data from 32 morphological characters. The average distance between breeds measured as a morphological index has a value of with extreme values of between Mastin del Pirineo and Mastin Espanol and of for the Gos d Atura - Sabueso Espanol pair. The morphological phylogeny obtained in this study confirms the classifications made previously by means of dental cranial historical and behavioral comparative criteria. The results suggest the formation of 2 large clusters one formed by the breeds belonging to the ancestral trunks Canis familiaris intermedins and Cams familiaris inostranzewi and the other which includes the members of the Cams familiaris leineri and Canis familiaris metris-optimae trunks.

A partir de I analyse qualitative et quantitative des données provenant de 32 caractères morphologiques on a étudié les relations existant entre 10 races canines espagnoles. La distance moyenne entre-races mesurée par un indice de distance morphologique prend une valeur de 4 228 i 0 681 avec des valeurs extremes de 1 732 entre Mastin del Pirineo et Mastin Espanol et 5 099 pour le couple Gos d Atura - Sabueso Espanol. La phylogénie morphologique obtenue dans ce travail confirme les classifications précédentes réalisées à partir de .
