Genetic structure of black poplar (Populus nigra L.) population in the area of Great War Island

摘要

The genetic structure of black poplar (Populus nigra L.) populations in the area of Great War Island (GWI) was studied at the level of 30 genotypes, based on microsatellite molecular markers (SSR). Eleven polymorphic SSR loci were used for analysis of intarpopulation genetic variability. Observed and expected heterozygosity in studied population were high (0.70 and 0.82). The fixation index calculated for single locus ranged from -0.055 (PMGC_14) up to 0.424 (PMGC_2607), while the mean value was 0.143. Deviation from Hardy-Weinberg equilibrium (HWE) differed between single loci. Stabile genetic structure and satisfactory level of genetic variability that have been determined at the population level represent a good starting point for conservation and sustainable use of the available gene pool and further breeding of this species.
