Biofertrilizers are preparations containing agriculturally useful microorganisms which help in mobilizing plant nutrients through their biologyical activity.  Rice (Oryza sativa L.) is the stable food for half of the world’s population.  The aim of application of biofertilizers is to get fast growth, better health and yield.  Successful crop improvement programme depends on availability of sufficient genetic variability that arises from genetic diversity DNA markers, being independent of environment interference are indispensable tools in the study of genetic variability.  RAPD markers have been used to characterize variation at the DNA level.  This study clearly indicated that the combined effect of biofertilizers showed variation in the genetic diversity of oryza sativa variety TPS-3 and Ambi-16.
