Eleven isozyme systems were investigated in wild boar (Sws smofaferus L.) by means of horizontal starch gel-electrophoresis using liver and kidney extracts. Samples of 103 specimen that originated from three adjunct localities from Rhineland-Palatinate (Fed. Rep. Germany) were analysed. AAT, ACO, GDH, GPDH, LDH, ME, MPI, MR, PGDH, and PGI were invariant. Genetic olymorphism is described for PGM. The genetic polymorphism at PgmZ is explained by a bialhic model. Observed genotypic structure dld not differ significantly from Hardy-Weinberg-proportions at this gene locus. The degree of heterozygosit is 58,3 % and Wright's Fixation Index F = -0.166 at Pgm2. The allelic structure at this ene Lcus differed to a great extent was only found in relative low frequencies compared to wild boar. The genetic polymorphisms were moderate in the wild boar population compared to electrophoretic data of other animal species.from that found in domestic swine, i. e. in domestic swine t a e faster migrating PgmZ allozyme
