Abstract

We report the characterization of 28 polymorphic microsatellite markers in Linum usitatissimum that allow distinguishing almost all cultivars of both flax and linseed. Polymorphism was low, ranging from two to 10 alleles per locus in the 93 cultivars screened. Linkage disequilibrium was found at about a third of the pairs of loci likely due to self-fertilization and strong selection by breeders. We tested these loci for cross-amplification in nine additional species of Linum and found that three species amplified a majority of loci.
