The aim of this study was to contribute new data on autosomal STR and Y-STR markers of the Majhi tribal community of Chhattisgarh, a state of central India. In order to improve available databases of forensic interest, we analyzed 15 autosomal STR markers in a population sample of 129 unrelated indigenous Majhi tribe and 23 Y-chromosomal STR markers in the 107 males of the sample. The combined power of discrimination (CPD) and combined power of exclusion (CPE) were greater than 0.999999 and 0.999998 respectively for autosomal STRs. In addition, a total of 64 distinct Y-STR haplotypes were observed out of which 31 Y-STR haplotypes were observed only once. The haplotypes diversity and discrimination capacity for 23 Y-STR loci was 0.989 and 0.589, respectively. The highest gene diversity values at the single copy locus DYS570 and the multi-copy locus DYS385 a/b were 0.805 and 0.952, respectively. Average gene diversity over loci was 0.652304 ± 0.325572.
