Assessment of genetic diversity is a key factor in germplasm characterization and conservation. An investigation was carried out with 20 rice genotypes constituting checks collected from different sources using 13 microsatellite markers to study the nature and magnitude of genetic divergence. The results showed that all the SSRs were polymorphic with different alleles among the genotypes studied showing the robust nature of microsatellites in revealing polymorphism. The average PIC value was 0.349 and it ranged from a low of 0.090 (RM OSR) to a high of 0.572 (RM 495). The Jaccard’s similarity coefficient ranged from 0.231 to 1. The UPGMA dendrogram revealed two major groups with five clusters and the wide range of dissimilarity values (0.01-0.88) which represents a high degree of diversity among the genotypes. The results of the genetic diversity can be exploited for the selection of the parents for developing high zinc rice variety through molecular breeding program.

Key words: Microsatellites, Polymorphism, PIC value, UPGMA dendrogram.
