Abstract
Screening of thirty-two allozyme loci in Tor putitora yielded ten polymorphic loci, useful in determining genetic divergence in natural populations of the species. Samples from three different Indian rivers viz. the Satluj, Ganga and Garua were studied with the identified allozyme loci, to assess their suitability for genetic diversity analysis in T. putitora. The observed heterozygosity per locus varied from 0.0840 (Satluj) to 0.1245 (Ganga). The significant genotype heterogeneity was observed between the sample sets (P<0.05). The identified loci exhibited significant potential to determine population structure of T. putitora across its natural range of distribution.
