Zusammenfassung:Labeo rohita, popularly known as rohu is a widely cultured species in the whole Indian subcontinent. Knowledge of the genetic diversity of this species is important to support management and conservation programs which will subsequently help in sustainable production of this species. DNA markers, mostly microsatellite markers are excellent tool to evaluate genetic variation of populations. Genetic variation of three wild and one farm population was assessed using eleven microsatellite loci. In analyzing 192 samples, the number of alleles ranged from 4 to 23; observed heterozygosity 0.500 to 0.870 and expected heterozygosity from 0.389 to 0.878. Exact test for Hardy Weinberg disequilibrium revealed that each riverine sample had at least one locus not in equilibrium except one river. Negative inbreeding coefficients (FIS) were observed across populations indicating very high level of genetic diversity but little genetic differentiation among populations. •Genetic variation of Labeo rohita was assessed using eleven microsatellite loci.•Allele No. ranged from 4 to 23; HO 0.500–0.870 and He from 0.389 to 0.878.•Negative inbreeding coefficients (FIS) were observed across populations.•Very high level of genetic diversity was observed.•3.2% of genetic variation was due to genetic differentiation among L. rohita populations.
