Abstract:
Assessment of genetic variability in Punganur breed of cattle in Andhra Pradesh was carried out using 20 microsatellite markers. The mean number of alleles was 7.9±0.475 with a range of five to fourteen and allele size varied from 79 to 309 bp. The allelic frequency of microsatellite alleles varied from 0.0037 to 0.3824. Allelic richness obtained within the breed had a mean value of 6.17053 ± 0.29669. The mean observed and expected heterozygosity values were 0.0202 ± 0.0079 and 0.8384 ± 0.1946, respectively. The mean of within population inbreeding and Shannon index values were 0.9756 ± 0.0094 and 1.89044, respectively. Higher PIC (0.8171) value indicated the scope for maintaining variation in population. The Punganur cattle population studied was found to be deviated from Hardy-Weinberg equilibrium. High Inbreeding, shortfall of heterozygote’s and little genetic variation was noticed in Punganur population.
