DEVELOPING OF THE METHODOLOGY FOR THE IDENTIFICATION OF PICEA ABIES L. CLONES BY USING ISSR MARKERS
DescriptionThe 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

ASSESSMENT OF ENVIRONMENTAL PERFORMANCE OF LARGE CITIES IN THE CONTEXT OF RAPID URBANIZATION
DescriptionThe article defines the basic characteristics of the environmental performance of urban areas. There was offered the system of environmental performance indicators, covering the basic characteristics of the environmental performance. There was developed the algorithm and calculating methodology of composite index of the environmental performance of major cities in the context of rapid urbanization. There was conducted the approbation of the methodology according to the data of major cities which are the administrative centers of the Russian Federation for 2008, 2009 and 2011. There was carried out the rating of major Russian cities based on the composite index of the environmental performance
