Abstract
The study of intraspecific genetic differentiation of the Cajanderi larch (Larix cajanderi) was carried out in the north–east of Asia — in Magadan region and on the Kamchatka Peninsula. Genetic diversity of the larch was investigated using eight nuclear microsatellite loci. SSR analysis revealed high level of genetic diversity of the Cajanderi larch in the Far North-East of Asia. Significant genetic differences between L. cajanderi samples from Magadan region and Kamchatka suggests early isolation of the larch on the peninsula.
