[Genetic diversity and differentiation of Gmelin larch Larix gmelinii populations from Evenkia (Central Siberia)].
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. 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.
