The development of marker-associated breeding requires the development of DNA marker systems that meet the needs of the breeding process. We are looking for the opportunities to improve the efficiency of breeding for high oleic acid content in sunflower oil. One of the directions is the improvement of the existing marker system for detection the heterozygous status of the alleles of the FAD 2-1 gene. We carried out the search for information published in databases on this DNA locus. We studied the structure of the nucleotide sequences of the mutant allele and the wild-type allele. We proposed the way of improving the existing marker system.
