Genetic diversity within species of two species woody plants populations in Perm krai

Researched 3 Scots pine populations ( Pinus sylvestris L., Pinaceae ) and 3 populations of western species of Siberian larch ( Larix sibirica Ledeb., Pinaceae ) in Perm krai for genetic diversity within species detecting. 114 ISSR-PCR P. sylvestris markers and 116 ISSR-PCR L. sibirica markers were amplified. The rate of polymorphic loci expected heterozygosity and number of rare ISSR-PCR markers were identified. Researched species are characterized by high genetic diversity. The rate of polymorphic loci is higher in P. sylvestris ; expected heterozygosity and the number of effective alleles is higher in L. sibirica. Each species has populations with high and low genetic diversity parameters. The rare alleles were identified in every of 6 researched populations, but the number ranges from 6 to 13 in P. sylvestris populations and from 3 to 10 in L. sibirica populations. Genetic structure of researched populations analysis show that the interpopulation component of genetic diversity accounts for 30...
