Genetic Diversity of Siberian Larch from Uzhur Forest-Steppe Zone (Krasnoyarsk area)
Genetic diversity of Siberian larch (Larix sibirica Ledeb.) from Uzhur forest-steppe zone (Krasnoyarsk аrea) was inferred from data on 22 genes determining allozyme diversity of 13 enzymes. As it was established 22,73% of genes were polymorphic. In average, each tree was heterozygous in 9,8% genes. With Wright's F statistics, average individual inbreeding was estimated -34,1% relative to the population (Fis) and -26,2% relative to the species (Fit). Intrapopulation variability accounted for more than 99% of the total, while the interpopulation variability was 0,8% (Fst = 0.0077). Genetic distance between populations was 0.0016.
