A precise understanding of genetic diversity and relatedness of Pinanga dicksonii (Roxb.) is an important component in its genetic improvement and germplasm conservation. P. dicksonii is an understory endemic palm of Western Ghats of Karnataka. The genetic diversity analysis among nine genotypes of P. dicksonii has been carried out using SSR markers. Among the 10 tested SSR markers, 9 successfully revealed polymorphism, SSRs demonstrating 123 alleles in total, with a range of 20 to 22 alleles at each primer. Allele frequency at each locus ranged from 22.22% to 100% with a mean of 71.92%. The PIC of each primer varied from 0.25 to 0.87 with an average of 0.38. The UPGMA-based clustering analysis performed by NTSYS pc program (version 2.0) revealed that among the 9 studied genotypes, there was a high level of polymorphism among some genotypes, as well as genetic similarities, with index values ranging from 0.473 to 0.928.
