in wild boars from North-East of Poland

The aim of this study was to characterize the polymorphism of genes RYR1, LEP, GH, MYOG, MYF5 and GDF8 in wild boar population inhabiting North-East of Poland. The above genes are considered candidate genes for carcass quality traits in domestic pigs. Ninety animals were tested. Genes RYR1, LEP and MYF5 appeared to be monomorphic, whereas genes MYOG, GH and GDF8 showed polymorphism similar to that observed in European pig breeds. However, no PCR product was obtained for several animals when MYOG and GDF8 gene fragments were amplified, suggesting the difference between wild boars tested and domestic pig in sequence of the gene regions where primers annealed. Moreover, this suggests a possibility of identification of new variants of these genes in wild boar. KEY WORDS: gene polymorphism / pig / wild boar The species of wild boar, which is widespread in Europe, Asia and North Africa, in-cludes about 27 subspecies [Herre and Rohrs 1977, Epstein 1984]. The polymorphisms of blood group systems and blood proteins were characterized in several wild boar subspe-cies showing marked differences within and between subspecies and populations [Hartl et al. 1993, Tikhonov and Bobovich 1997]. Mitochondrial genetic variation was used to investigate the relationship between two Japanese wild boar subspecies [Watanobe e
