Studies on DNA polymorphism and genetic diversity among rainfed lowland rice genotypes

In the present study, 38 rainfed lowland rice genotypes differing in their submergence tolerance potential were used to study the DNA polymorphism and genetic diversity among these genotypes with the help of eleven RAPD markers employing PCR (polymerase chain reaction) based methods to identify divergent parents and generate mapping populations for tagging submergence tolerance loci in tolerant varieties using molecular markers in a long run.
