Abstract: Hallikar breed of cattle, popularly known as the ‘champion of draft breeds’, is a typical Mysore type cattle. Molecular characterization of Hallikar cattle through automated genotyping of 22 microsatellite loci revealed a total of 166 alleles with the number of alleles ranging from 3 (ILSTS033) to 16 (TGLA53) with a mean of 7.55±0.65, and the mean effective number of alleles was 3.67±0.31. The sizes of the alleles ranged from 92 (CSRM60) to 302 bp (ILSTS006). The overall mean polymorphic information content value was 0.6367±0.03. The observed (Ho) and expected heterozygosity (He) values averaged 0.6068±0.05 and 0.6863±0.03, respectively, measuring high genetic variation in the population. The overall mean deficit of heterozygotes (FIS) (0.1314±0.05) exhibited existence of a breed structure in Hallikar.
