Molecular-genetic differentiation of genotypes of birch on the basis of SSR-markers’ polymorphism

Abstract

The article discusses the use of microsatellite (SSR) markers for the estimation of genetic resources of birch. It is shown that DNA analysis using 12 microsatellites is most suitable for intraspecific differentiation of selectively valua-ble genotypes of this tree species. The genetic polymorphism in the studied birch genotypes was determined from the loci examined by SSR. Multilocus genetic passports were prepared for 31 samples of birch, which allowed (based on the presence (1) / absence (0) of 36 alleles) to identify the investigated samples.
