A comparison of quantitative and qualitative performance of the selected clones of breeding of A.S. Yablokov and S.N. Bagaev has been made. At the same forest conditions, the clones are much higher than regular at reserves, the absolute completeness, the average heights and diameters of trees. Gigantic forms of P. tremula L. are resistant to infectious diseases, and at the fifth grade are characterized by good sanitary condition. We have also shown the economic feasibility of using of fast-growing clones in the genetic reserve for the organization of giant aspen of P. tremula L. plantation

The technology for the identification of Picea abies L. clones by using ISSR markers was developed. 9 ISSR primers ((GA)9T; (AC)8C; (CA)6RY; (CA)6RG; (CA)6(GT); (CA)6(AC); (AG)8T; (GA)8С и (AG)8YT) were recommended to use for genotypes detection. The selected primers have shown the high level of polymorphism. A total of 172 amplified fragments were found by the selected primers and 149 (86.6%) of them were polymorphic

In the article we have conducted the estimation of breeding population of salix acutifolia. We have studied the following indicators of the measured trees: the percentage of salicylates, bark content in relation to the wood. For these two indices we have calculated the "complex" productivity of the trees. Based on that, the trees are assigned to these breeding categories: Category 1: trees with high productivity - ( 49.7 - 39.9 kg / t of raw materials) Category 2 : trees with average productivity - ( 39.1 - 33.8 kg / m raw materials) category 3 : trees with low productivity - ( 31.8 - 24.3 kg / t of raw materials)

The possibility of the ISSR-markers application for systematization and genetic certification of the genus Rhododendron is showed on the basis the research of 25 species and intraspecific taxons. The way of recording of genetic passport on the basis of amplicons size is suggested

In order to identify high-genotypes in natural stands of Sacutifolia Willd we worked to identify the categories of breeding trees. Experimentally proved, that for breeding to increase the productivity of bark of Salixacutifolia Willd the selection would be best carried out with plants, the diameter of the barrel of which is in the range of 9 to 16 cm, tree age 15 - 19 years

The genetic variability study of Pinus sylvestris trees appurtenant to different selection categories in the plus stand is carried out with ISSR markers. A total of 178 loci were amplified by 6 ISSR – primers and 168 of them were polymorphic. It is detected that the genetic distance between the trees appurtenant to difference selection categories varies from 0,038 to 0,082. Genetic variation parameters of the Pinus sylvestris plus stand are calculated. Shannon’s index (I) was 0,4303, Nei’s gene diversity (H) was 0,2735 and Effective number of alleles (Ne) was 1.4268

In this article, we have presented the survey of populations of triploid plant of Populus tremula L. genetic reserve of aspen in the area of Sharinsk in the Kostroma region. We have found the population of P. tremula L. not affected by the Phellinus tremulae Bond. et Boris fungus. The morphological and cytological analysis of plant samples taken from this genetic reserve in 1961 has been made. It has finally confirmed the triploid nature of the samples

We have studied the growth of larch plantations in the Republic of Mordovia in order to assess the breeding and selection of candidates for plus trees

The article gives the overview of the non-invasive method of NMR relaxation and assess the efficiency of using this method in the study of cultured under in vitro plant objects on the example of Rosa hybrida plants
