RELATIONSHIP BETWEEN GENETIC AND ENVIRONMENTAL CHARACTERISTICS OF LITHUANIAN POPULATIONS OF PURPLE LOOSESTRIFE (LYTHRUM SALICARIA)

The present study evaluated genetic diversity of Lithuanian populations Lythrum salicaria in relation to parameters riparian environment. Growing along Nemunas, Seaside and Lielupė river basins, 15 were examined using amplified fragment length polymorphism markers. Molecular data related the type land use cover, natural vice versa regulated fragments rivers. Population mean as follows: percentage polymorphic loci (57.2), expected heterozygosity (0.183), polymorphismc information content (0.218). Mantel test revealed correlation (R2 = 0.0986, p 0.01) between geographic distance populations. Greater within, rather than among (ΦPT 0.213) was observed. According Bayesian clustering, studied are admixtures two gene pools. Analysis molecular variance significant differentiation belonging distinct from vs.
