Abstract

The recovery of AAGTs represents an example of integration between environmental and productive goals. The aim of this study was to privide, by means of typification of 41 subjects to 19 microsatellite loci, a first contribution to the knowledge of the genetic variability of 'Nero Lucano', whose origins could go back to the ancient pig present in Lucania region (Italy). The results, within the limits of the observation filed, evidenced an average allele number per locus equal to 3,2±0,89 (c.v. = 28 %) ranging from 5.0 for SW 2038 locus and 1 for SO 386 locus; on the contrary, the latter locus is polymorphic in other 12 AAGTs (2-9) alleles). The mean observed and expected heterozygosity were 49,13 ± 22,44 (c.v. = 46 %) and 47,86 ± 18,02 (c.v. = 38 %), respectively. These preliminary results must be confirmed by increasing sampling. Indeed, monomorphism of SO 386 locus might be used for genetic discrimination of meat and its. products.
