Аннотация: The genetic diversity of SSR markers was studied in six populations of Siberian larch, two popu-lations of Gmelin larch, and four populations of Cajander larch. Seven pairs of nuclear microsatellite loci were used for this analysis. 103 allelic variants were detected in 365 individuals of three species of larch. According to the AMOVA results, the variability proportion that characterizes the differences between three Larix species was twice as higher (15%) than the proportion that accounts for among-population differences within the species (6%). The differentiation of the populations of three species of larch based on SSR markers exceeded 12% (F (ST) = 0.121). A significant correlation of the genetic distances with the geographic distances between populations was found (r = 0.835, P = 0.01).

Аннотация: Within- and among-population diversity of Gmelin larch Larix gmelinii (Rupr.) Rupr. from Evenkia was inferred from data on 17 genes determining allozyme diversity of ten enzymes. More than 50% of the genes proved to be polymorphic. On average, each tree was heterozygous at 9.2% genes. Heterozygosity expected from the Hardy-Weinberg proportions was higher, 12.5%. A deficit of heterozygous genotypes was observed in all populations under study and attributed to inbreeding. With Wright's F statistics, average individual inbreeding was estimated at 26.6% relative to the population (F-IS) and at 27.8% relative to the species (F-IT). The greatest deficit of heterozygosity was observed for the youngest population II. Within- population variation accounted for more than 98% of the total variation, while the contribution of among-population variation was 1.66%. Genetic distance between populations varied from 0.0025 to 0.0042, averaging 0.0035.
