Abstract

Molecular characterization of cattle breeds is important for the prevention of germplasm erosion by cross breeding. The present study was carried out to characterize two Indian cattle breeds, Ongole and Deoni using microsatellite markers. Using 5 di-and 5 tri- nucleotide repeat loci, 17 Ongole and 13 Deoni unrelated individuals were studied. Of the ten loci, eight revealed polymorphism in both the breeds. The di-nucleotide repeats loci were found to be more polymorphic (100%) than tri-nucleotide repeat loci (60%). A total of 39 polymorphic alleles were obtained at 4.5 alleles per locus in Ongole and 4.1 in Deoni. The average expected heterozygosity was 0.46 (

    +
0.1) and 0.50 (
    +
0.1) in Ongole and Deoni breeds, respectively. The PIC values of the polymorphic loci ranged from 0.15 to 0.79 in Ongole and 0.13 to 0.80 in Deoni breeds. Six Ongole specific and three Deoni specific alleles were identified. The two breeds showed a moderate genetic relationship between themselves with a FST value of 0.10.
