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.
