Abstract: Rice is the world’s most significant cereal crop. It is always desirable to enhance the yield and improve the quality of rice in order to meet the demands of the world’s population. One of the basic criteria for genetic up-gradation of rice varieties is the exploration of gene pool divergence in current rice germplasm. In this study, genetic diversity assessment was performed to find the variations among 27 rice genotypes with the help of seven polymorphic Simple Sequence Repeat markers. The ranges of Polymorphic information content (PIC) value and effective allele per locus of microsatellite were 0.431-0.7435 and 1.757-3.898 respectively. Based on the constructed dendrogram on NTSYS-pc Version 2.20 program, the genotypes were grouped into two clusters having two sub clusters in each group. In future breeding program, this analysis of genetic diversity will be effective for selecting desirable rice genotypes as a donor by breeders.
