Assessment of genetic diversity and molecular characterization among elite rice varieties of bangladesh is very important for germplasm management varietal identification and dna fingerprinting thirty four microsatellite markers were studied across 21 types of rice to characterize and discriminate among different varieties. Rice blast disease caused by magnaporthe oryzae is one of the most destructive disease causing huge losses to rice yield in different parts of the world therefore an attempt has been made to find out the resistance by screening and studying the genetic diversity of eighty released rice varieties by national rice research institute cuttack nrvs using molecular markers linked to twelve . Dna markers have enormous potential to improve the efficiency and precision of conventional plant breeding via marker assisted selection mas the large number of quantitative trait loci qtls mapping studies for diverse crops species have provided . To study genetic diversity and population structure at molecular level different types of dna markers can be used however simple sequence repeats ssrs tautz 1989 and single nucleotide polymorphism snp markers are the most preferred markers now a daysthese dna markers are frequently applied for genetic diversity evaluation population structure assessment for inferring .
