The karyotypes of the 80 wild boars of the four subspecies, Sus scrofa ussuricus Heude from the Far East of USSR, S. s. nigripes Blanf. from Kirghizia (the Middle Asia), S. s. attila Thos. from Azerbaijan, S. s. ferus from Lithuania, Byelorussia and Central Russia, and the 44 domestic pigs of the five different breeds (Vietnamese Black, Siberian Omskaja Gray, Kakhethian-aborigen Georgian, Mangalica Hungarian, Landrace Swedish), were studied by the Giemsa Banding Method. Differential staining by the G-Method made it possible to identify all the homologous chromosomes of the wild and domestic pig karyotypes as well as to reveal the polymorphism of wild boar karyotypes (2n = 36, 37 and 38), which are determined by the two types of chromosome translocation. Crosses between domestic pigs (2n = 38) and wild boars (2n = 36 and 37) with different chromosome rearrangements might help to clarify the genetic function of the chromosomes A4, B3, B4, B5 and allow their use as genetic markers.

Comparative studies of immunogenetic features in domestic pigs and their ancestors, different subspecies of the wild boar, are of interest from an evolutionary viewpoint and promote our understanding of phylogenetic relationships. The antigen frequencies of factors in 10 genetical blood group systems, the gene frequency of their alleles and genotype frequencies were studied in 171 wild boars of different subspecies: 79 Far Eastern boars (Sus scrofu ussuricus Heude) from Primorye Territory and Amur region, 68 Middle Asian boars (Sus scrofu nigripes Blanford) from the Sari-Chelekski reservation of Kirghizia and 29 Transcaucasian boars (Sus scrofu uttifu Thomas) from Azerbaijan. In this study Buschmann's (1965) and Wiatroszak's (1970) data concerning blood groups of the West European wild boar along with the date we have obtained in blood group investigation of a large number of pig breeds originated in USSR and other countries (Tikhonov, 1967(Tikhonov, , 1972, were used for comparison. The animals were bloodtyped with monospecific sera which were entered in the International Pig Blood Group Comparison Tests (1964.The comparison of blood groups of the above-mentioned wild boar subspecies have demonstrated wide differences between them. The salient feature was the polymorphism revealed for the G and the F systems. These systems have been regarded
