Simultaneous identification of two MspI polymorphisms of the porcine myogenin gene in Hungarian breeds

Simultaneous analysis of two myogenin (MYOG) loci has been carried out using polymerase chain reaction‐restriction fragment length polymorphism (PCR‐RFLP) tests in DNA isolated from blood samples collected from four different pig breeds (Hungarian Large White, Duroc, Mangalica and Hungarian Landrace). The following MYOG^A frequency values have been obtained: Hungarian Large White 0.2416; Duroc 0.0900; Mangalica 0.6617; Hungarian Landrace 0.2361. The MYOG² allele was found in Duroc and Mangalica breeds only. This test allows the analysis of two loci of the MYOG gene in parallel, which might be used in marker assisted selection programmes in the near future. Ongoing studies on the possible effects of the MYOG types on carcass and growth traits are outlined.
