ABSTRACT                            

Submergence will affect rice crops at any stage of growth, either short or long term. The probabilities of survival are very low once utterly submerged during the crop’s vegetative stage. Water logging and floods cause substantial yield losses in cereal crops worldwide notably in rice. Plant breeders have discovered that the Sub1gene, confers resistance to submergence of up to fourteen days and the donor of this gene is FR13A (Dhalputtia),which is a local landrace of Odisha, India. So, understanding the molecular and physiological mechanisms of this trigger the development of flooding tolerance rice varieties. Now, the marker-assisted backcrossing method successfully allows the introgression of Sub1 genes to rice mega varieties for submergence tolerance.
