Flax (Linum usitatissimum L.) is known as a dual-purpose crop, producing both fiber and oil, which have wide range of uses. Successful flax breeding requires knowledge on the genetic determinants traits. The former identification molecular markers for valuable traits used labor-intensive sometimes poorly reproducible approaches. However, they allowed an assessment diversity its relatives, construction linkage maps, some important characteristics. sequencing whole genome triggered development genome-wide association studies (GWAS) quantitative trait locus (QTL) mapping. QTLs nucleotides (QTNs) were identified seed- fiber-related features resistance to biotic abiotic stressors. Cost-effective accurate analysis large number genotypes multiple simultaneously using microarrays or targeted deep became available, well HRM, TaqMan, KASP, other fluorescence-based high-throughput methods detecting DNA polymorphisms. most in are ambiguously linked expression not universally applicable. A major challenge remains lack functional To date, only few known, mainly mutations FAD3 genes responsible reduced linolenic acid content linseed oil. For further marker-assisted genomic selection flax, it necessary analyze exhaustively phenotyped sample sets, identify polymorphisms that determine traits, develop efficient test systems.
