Abstract
Rice is a unique crop which is generally grown in submerged soil. However, not all rice varieties according to its genotype can tolerate to complete flooding. The selection using DNA markers is now frequently used in real breeding programs, including for the development of submergence-tolerant rice. This review summarizes the researches devoted the problem of breeding of submergence tolerant rice. Data on mechanisms, adaptation strategies, loci associated with tolerance to this stress are given. We had placed great emphasis on investigations aimed at application of molecular-genetic markers in the breeding of complete flooding tolerant varieties.
